Thanks and I understand.

1. We would not have arrived early to the airport. The flight was delayed in PTY well before we were informed.
2. As prefer silver on a miles ticket I do not expect much but by us ending in PTY it is cheaper for Copa to move others continuing on after PTY. That is great for Copa, other passengers but not us.
3. You are rifght but it Copas's app. Once I informed them of the first issue with app not updating gate changes the back office should have been notified and had it resolved before the gate change for our second flight but my guess there was and probably still no notification. Yes take off early if everyone is on board.
4. Depends on how late is used but we missed the chance to board the plane.
