2:55pm JFK-CUN changed to 9:15am in July. Went from 2 daily flights to 1.
Called in and they proactively offered us PHL-CUN at any timing of our choosing. PHL still has 3 flights daily. Considering we paid $633 for an I class ticket, they're now $1800 from Philly and $2,000+ from JFK.
We're happy with their solution. We'd rather go out of Philadelphia anyways, but JFK was so much cheaper when we booked last month. Good job AA, they get to sell $2K tickets from JFK and we get to fly out of our home airport. ^
