Hello,
it appears like there is great availability of Copa tickets on MileagePlus through Jan 4, 2020 and then absolutely nothing (everyday or saver) after that date. In the past they were offering seats 330 days in advance. Frequent flyer tickets are still available in January through Copa’s own ConnectMiles program.
I called United and they were not aware of any issues with Copa (unlike other airlines). Does anyone know whether there are changes in booking codes, IT or policies that would explain this?
Thanks!
