What is the Order Number and reservation code?

You should know that we now use Order Nº to identify your purchase in LATAM; it includes flights, additional services and extras for your trip.

If for some reason you did not receive it with your boarding pass, enter My trips with your email and you can get it. 

The reservation code still exists for some tickets purchased in our classic version and to perform some actions in our new experience. You can find it on the unique proof of sale, which comes in the purchase confirmation mail.
