In response to fan feedback, the Eagles have decided to offer season ticket holders a deferred payment option that would allow them to wait until the NFL's labor situation before being charged for their tickets. This will apply to the second season ticket payment that's coming due soon.
For those that have already paid and anyone that doesn't want to defer, the team has guaranteed that it will refund season ticket payments with interest should the NFL season miss games or be canceled altogether.
So either way, if you're a season ticket holder, you're covered.
