Hello' exceladdict
Thinking of you, frequent flyer Avianca Brazil, and the close relationship we have developed over time, created the PAL - our loyalty program. We believe that you, our FRIEND who always travels with us, deserves our recognition and differentiated attention.
With PAL you accumulate points and can turn them into tickets to travel on our flights or on our Airline Partners.
You can collect points faster with our non-airline partners such as credit cards, for example.
The more points you collect, the more benefits you will get.
Your FRIEND number:
Enter your FRIEND number when booking or check-in on all your travels with Avianca in Brazil or our Airline Partners.
We appreciate your choice.
Staff FRIEND
