You open your reservation and see two airline names on one flight. The flight number belongs to one carrier, and a line underneath says another one is flying it. That is a codeshare, and it is completely normal. It does raise two fair questions for a visa file. Which website will show your booking, and will an officer be confused? This guide answers both, using what airlines and regulators themselves publish about codeshares. Where we could not find an official statement, we say so and give practical advice instead.
Codeshare reservations: key facts
| Question | What the official pages say |
|---|---|
| What is a codeshare? | ANA describes it as a flight carrying ANA's flight number but operated by a partner airline, and says customers are told which airline operates the flight when they book.[1] |
| Whose rules apply on the day? | ANA says the operating partner's rules apply to carry-on restrictions, check-in times and several conditions of carriage.[1] |
| Where do I check in? | At the operating carrier's counter, not ANA's, for ANA codeshares flown by partners.[1] |
| Who changes the booking? | Emirates says that when your booking is with Emirates on a flydubai codeshare, you contact Emirates for amendments.[4] |
| Must the operator be disclosed? | Under US rules, written confirmations for codeshare flights must show "Operated by" and the operating carrier's name.[3] |
What is a codeshare flight, in plain words?
Two airlines agree to sell seats on the same plane. The airline that actually flies it is the operating carrier. The partner that sells seats on it under its own two-letter code and flight number is the marketing carrier. One aircraft, one crew, sometimes four or five flight numbers.
ANA's own definition is a good one to quote: a codeshare is a flight with an ANA flight number that a partner airline operates. ANA adds that when a flight is a codeshare, customers are told at booking which airline will operate it.[1] ANA's list of international partners includes Air India, Lufthansa, Singapore Airlines, Turkish Airlines, United and many others.
Airlines do this to sell journeys they cannot fly alone. A carrier with no planes going to a smaller city can still sell you a through journey there, using a partner for the last leg. For you, that often means a single booking reference covering the whole trip.
Marketing carrier vs operating carrier: who does what?
The division of jobs is not identical across airlines, which is exactly why reading your own airline's page matters. Here is what two official sources say, side by side.
| Topic | Marketing carrier (sold the seat) | Operating carrier (flies the plane) | Source |
|---|---|---|---|
| Flight number on your booking | Its own code and number | Has its own number for the same flight | ANA[1] |
| Check-in | Not at this airline's counter (ANA) | At the partner's counter | ANA[1] |
| Carry-on and check-in times | - | Operator's rules apply | ANA[1] |
| Checked baggage allowance | Emirates allowance applies for the whole codeshare journey | Even on a first sector flown by flydubai | Emirates[4] |
| Changes to the booking | Contact Emirates when the booking is with Emirates | - | Emirates[4] |
| Flight status | - | Use the operator's website and flight number | ANA[1] |
For a visa reservation, most of this is about the real trip rather than the document. The rows that matter now are the first and the last: which flight number is printed, and which airline's site you would use to check things.
How does a codeshare appear on a reservation?
Usually as the marketing flight number with an "operated by" line. US regulation spells this out. Under 14 CFR Part 257, written confirmations for codeshare flights must state "Operated by" followed by the corporate name of the transporting carrier. Schedules and itineraries must show the operator's name prominently next to each codeshare flight, and anyone selling by phone must tell you that the operator is not the airline whose code appears on the ticket.[3]
That US rule binds sales covered by US law, but the "operated by" convention is used widely elsewhere too. On a document in your file, it might read like this example:
- Example: Flight XX 4512, Delhi to Frankfurt, 14 November. Operated by Partner Airline. Booking reference ABC1DE.
Two practical points. First, the airport departure boards may list both numbers, but ANA notes that your boarding pass may show only the operating airline's flight number.[2] Second, if you search a flight tracker for the marketing number and get nothing, try the operating number. ANA itself advises searching for codeshare flight status with the operating carrier's number or by route.[1]
Where can a codeshare booking be looked up?
Start with the airline that holds the booking, which is the one named with the booking reference on your document. Its "Manage booking" page should open the reservation with the reference and your surname. Emirates, for instance, asks for exactly those two details.[5] The Emirates and flydubai page confirms the logic from the passenger's side: when your booking is with Emirates, Emirates handles the amendments.[4]
The operating carrier is a different matter. It does receive your details so it can check you in and board you. Whether its own website will open your booking with the marketing airline's reference is not something we found stated as a general rule on any official page. In practice it can depend on the airlines involved, and the operator may keep the record under a reference of its own. ANA's guidance for its domestic codeshares hints at this split: make changes on ANA's website first, then complete online check-in on the operating airline's site.[2]
Practical rule: to confirm a codeshare reservation exists, use the website of the airline whose booking reference is printed on it. Do not assume the operating airline's site will show it under the same code.
The walkthrough on pre-appointment PNR checks shows what a successful lookup looks like. If you want the background on what a PNR is and how airline systems share it, read what a PNR number means and how reservation systems work.
What does a visa officer make of a codeshare?
Codeshares are routine, and officers see them constantly. Nothing in the checklists we have read treats them differently. Germany's tourism checklist asks for a "Flight reservation",[7] and the Visa Code treats a reservation as acceptable evidence of travel plans.[8] Neither cares whether a segment is flown by a partner.
The only real risk is confusion during a check. Picture an officer who sees "Partner Airline" in large type and tries the reference on that airline's site. If the booking is held by the marketing carrier, the lookup may fail even though the reservation is perfectly real. You cannot control how anyone checks, but you can make the right route obvious:
- Make sure the document clearly shows which airline issued the booking reference.
- In your cover letter, describe it accurately, for example: "flight reservation, reference ABC1DE with Airline X; the Delhi to Frankfurt segment is operated by Partner Airline".
- Verify the booking yourself on the issuing airline's site the day before your appointment.
Never call the reservation a ticket in your form or letter. A plain, accurate description is both honest and the easiest thing for an officer to follow.
Codeshare partnerships you may meet on Indian and Gulf routes
Emirates and flydubai. The two Dubai airlines sell connecting codeshare journeys. Emirates says baggage is checked through to the final destination on connections in either direction, and that its own baggage allowance applies across codeshare itineraries, including when flydubai flies the first sector.[4] If you connect from a flydubai flight onto Emirates, you may need to collect your onward boarding pass at the transfer desk in Dubai.
IndiGo and its international partners. IndiGo's codeshare page lists partnerships with airlines including Turkish Airlines, Qatar Airways, Air France, KLM, Virgin Atlantic, British Airways, American Airlines, Japan Airlines, Malaysia Airlines and Qantas.[6] A typical shape is a domestic IndiGo flight feeding a partner's long-haul service from a metro airport. We could not open IndiGo's page directly in October 2026, so confirm the current partner list there before relying on it.
Alliance partners. Star Alliance, with 26 member airlines,[9] is a common source of codeshares. ANA's partner list is a useful window into how widely its members code on each other's flights.[1]
Example: say you live in Coimbatore and your Schengen trip is to Munich. A partner itinerary could take you to a metro on a domestic flight, then onward to Germany, under one reference. The officer sees one coherent journey from your home city, which is exactly what you want.
Codeshare, single airline or separate bookings?
| Option | Strengths for a visa file | Weak spots | Our take |
|---|---|---|---|
| Single airline, own metal | One name on everything; one site to check | Not available from every city | Simplest when it exists |
| Codeshare on one booking | One reference from your home city to destination | Two airline names can confuse a quick check | Fine; describe it clearly |
| Separate bookings on two airlines | Flexible for the real trip | Two references; officer must join them | Better bought after the visa |
For the deeper question of which carrier to pick in the first place, see which airline your reservation should be on. Budget carriers bring separate issues, covered in reservations on low-cost airlines.
How to verify a codeshare reservation, step by step
- Find the booking reference and the airline named with it on the document.
- Open that airline's Manage booking page, not the operating partner's.
- Enter the reference and surname exactly as printed.
- Check each segment: names, dates, flight numbers and any "operated by" note.
- Match the dates to your hotel, insurance and application form.
- Save or print the page if your visa centre accepts extra evidence; otherwise just note that it checks out.
- Contact us before your appointment if anything does not match.
Timing still applies. The hold lasts at most 2 weeks, the carrier choosing the precise cut-off, so a couple of days before the appointment is the sweet spot. More on reservation validity.
Getting a reservation, with or without a codeshare
Our documents carry a live PNR under your name for the journey you specify. The airline holding the booking is printed next to the reference, which tells you which website to check. Because it is only held, not purchased, you cannot travel on it.
Each figure is for one person, outbound only or there-and-back; on multi-city plans every two legs are priced as a pair. Pay via Razorpay using UPI, card or netbanking; our email normally arrives about ten minutes later. See the full price list, how a visa flight reservation works, or the DummyTicketPrice home page.
Prefer a single airline throughout?
Say so in the notes box and we will take it into account for your route.
Following an order? Use order tracking. Hotel evidence is available through our hotel booking page, and country rules are on reservation requirements by country. For Schengen specifics, read the Schengen guide; for one-way trips, see onward tickets.
Keep in mind: a reservation supports your file; it cannot secure a visa. The consulate makes that decision.
Codeshare reservations: frequently asked questions
Which airline's website should I use to check a codeshare booking?
Use the site of the airline that issued the booking reference, which is normally the marketing carrier named with the reference on your document. Enter the reference and surname on its Manage booking page. The operating partner may not open the same reference on its own site, so a failed lookup there does not mean the booking is missing.
Will a codeshare look suspicious to the visa officer?
No. Codeshares are an everyday part of airline networks, and the checklists we have read treat a reservation the same way whoever flies the plane. Make the document easy to follow: the issuing airline and reference should be clear, and your cover letter can describe the operated-by segment in one plain sentence.
Why does my reservation show a different flight number from the airport board?
Because one flight carries several numbers. Your booking uses the marketing carrier's number, while boards and boarding passes often lead with the operator's. ANA notes that a boarding pass may show only the operating airline's number. For flight status, search the operator's number or the route.
Whose baggage rules apply on a codeshare?
It depends on the airlines. ANA says the operating partner's rules apply to carry-on restrictions and check-in times, while Emirates says its own baggage allowance applies across codeshare journeys with flydubai. Read the conditions of the airline you book with when you buy the real ticket after your visa.
Where do I check in for a codeshare flight?
Usually with the operating carrier. ANA tells passengers on partner-operated codeshares to use the partner's check-in counter rather than ANA's. When you travel for real, check the departure terminal for the operating airline, because it can differ from the marketing airline's terminal.
Can I ask for a reservation without codeshare segments?
Yes. Add it to the notes box when you book. On many routes a single airline flies the whole journey, and that keeps everything on one website. Where only a partner serves part of the route, a codeshare on one booking is usually tidier than two separate reservations.
Does the "operated by" line have to appear?
US regulations require written confirmations for codeshare flights sold under US rules to show "Operated by" and the operating carrier's name. Other markets commonly follow the same convention. Either way, it helps your file, because it tells anyone reading which aircraft you would board.
