I am flying TP208 on 9/15 JFK-LIS.
I had a look at the upgrade policy on TAP, and noticed this page:
https://www.flytap.com/en-pt/booking...d=filters-tab3
Apparently if there is available Executive Class (Business Class) seating, I can upgrade at the check in counter for $479 one-way.
The current plusgrade bid is in the $700s. So could this potentially mean I just need to go to the airport early, pay for the upgrade at check in, and fly business class without having to be the top bidder?
