A passenger presents themselves at check-in with a ticket in the name of “Marie Dupont,” but their passport states “Marie-Claire Dupont-Martin.” The counter refuses to modify anything, and the flight departs in two hours. This common scenario costs hundreds of euros each year in change fees or repurchased tickets.
Choosing the right name when booking a plane ticket relies on a simple reflex: copy exactly what appears on the travel document used on the day of departure.

MRZ Zone of the Passport: The Only Reliable Reference for Your Plane Ticket
It is often thought that the “official” name is the one used in daily life. In practice, the airline compares the name on the ticket with the machine-readable zone (MRZ), those two lines of characters at the bottom of the passport photo page. It is this zone, and not the top of the document, that is authoritative during the check.
Open your passport to the photo page. At the bottom left of the MRZ, you will find your last name, followed by your first name. Copy these elements letter by letter, without adding a second or third name unless the airline explicitly requests it.

Special characters (accents, cedillas, umlauts) are absent from the MRZ. “François” becomes “FRANCOIS,” “Héloïse” becomes “HELOISE.” Most booking systems do not accept accents. Therefore, they can be omitted without risk, provided that the basic spelling is not altered. For those who wish to book on Voyage 2 Rêve, the logic remains the same: the name entered must match the MRZ of the document presented at the airport.

Birth Name or Spouse’s Name on the Ticket: What Rule to Apply
After a marriage, the passport may mention either the birth name alone, the spouse’s name alone, or both. The ground rule is straightforward: use the name that appears in the MRZ of your current passport.
If the MRZ only indicates your birth name, book with that name, even if you use your spouse’s name everywhere else. If both names appear in the MRZ, you can indicate either one or both. A few concrete points of caution:
- A passport renewed after marriage may display both names in the MRZ while the old one showed only one. Check at each renewal before booking.
- The French identity card does not have an MRZ identical to that of the passport. For flights outside Schengen, only the passport counts. For intra-Schengen flights with an identity card, copy the name as it appears on the card used on the day.
- If you booked with your birth name and then changed your passport in the meantime, the new document must still contain that birth name somewhere for the match to occur.
Compound First Name and Hyphens on a Plane Ticket: Traps to Avoid
The case of “Jean-Pierre” illustrates a recurring problem. Some booking forms do not accept the hyphen. One hesitates between “Jean Pierre,” “Jeanpierre,” or “Jean.” A compound first name must be entered in full, with a hyphen or space depending on what the form allows.
If the field rejects the hyphen, merge the two parts (“JEANPIERRE”) or separate them with a space. Most airlines tolerate this variation as long as all letters are present and in the correct order. Omitting the second part of the compound first name, however, can pose a real problem at boarding.
Particles and Apostrophes in Last Names
Names with particles (“de,” “van,” “du”) and apostrophes (“O’Brien,” “N’Diaye”) undergo the same treatment. The MRZ generally removes spaces and apostrophes. “Van de Laar” becomes “VANDELAAR” in some systems. Attach the particle to the name if the form blocks the space, and check the result on the booking confirmation.

Correcting a Name Error After Booking: Deadlines and Flexibility
A typo noticed right after purchase is often corrected without charge. Several airlines allow a grace period (usually within the first hours after booking) during which a minor correction remains free. After this period, practices vary: some airlines charge fixed fees, while others require cancellation and repurchase of the ticket.
The distinction between “minor correction” and “name change” is crucial. Switching two letters (“Dupnot” instead of “Dupont”) falls under correction. Replacing “Marie Dupont” with “Claire Martin” constitutes a passenger change, an operation that most airlines refuse or charge heavily for.
Check the name on the booking confirmation within minutes of purchase. This is the only time when correction remains simple and free with almost all carriers.
Low-Cost Airlines and Name Rigidity
Low-cost airlines often apply stricter policies. An error of two or three characters may already be considered a paid name change. With these carriers, reviewing the summary before confirming payment is not generic advice: it is the only real protection against disproportionate fees relative to the ticket price.
Digital Identity and Ticket Booking: What’s Changing
The arrival of France Identité and the eIDAS 2.0 regulation in Europe opens an interesting avenue. Some airlines and agencies are beginning to offer auto-filling of the name from the passenger’s official digital identity, which eliminates the risk of typos during entry.
The principle remains the same: the name on the ticket must strictly match the digital identity used. If your digital identity is linked to an expired passport or an old civil status, the match will fail at check. Before using this feature, ensure that the source document of your digital identity is indeed the one you will present at the airport.
The reflex to maintain, regardless of the booking channel, can be summed up in one sentence: open your passport, read the MRZ, copy. Everything else, usual first name, nickname, spouse’s name used daily, does not count at the time of boarding.
