The "booking code" is a random combination of letters and numbers associated with a reservation when it is made to make it easier to search for later.
What does a booking code look like?
The flight code used by Iberia has 6 digits, which may be preceded by a shared part (1A/).
Example: 1A/ 7NS7PZ
Always enter the 6 digits of the booking code that come after (1A/).
Where can I find the booking code?
You may find it in your receipt - ticket itinerary -.
Example .- Electronic ticket receipt at Iberia.com.
If you bought your ticket at an office or travel agency, the document may vary but the booking code will always have the same format.
