# What to do if a passenger has a long last name or has only one name?

📏 **Passengers with a last name that is too long**
There is a limit for the number of characters in the surname field.

If you are booking a **low-cost flight that is non-refundable at all**, meaning, there is no free cancellation period:
Ask us in chat how to register the passenger surname before booking.

If you are booking a **regular airline that has a free cancellation** period:
1. Write as much of the surname as possible, making sure the last surname is present.
2. Make the booking.
3. Let us know in chat the booking reference and full passenger’s surname as per passport.
4. Our support agents will review the booking and advise how to proceed.

☝️ **Passengers with only one name**
Make sure that you **write the name of the passenger exactly as it appears on the passport**. If the passenger doesn’t have a first name or last name, you should do the following:
1. Enter the information as per passport and leave the first or last name field empty (depending on what name your passenger is missing).
2. Click the “Book” button.
3. You’ll get a pop-up asking you if you’re sure that the passenger doesn’t have a first/last name or if you forgot to enter it. Confirm the message and the booking is made.
