Got this in the mail today:
Dear qasr,
Thank you for flying with JetBlue Airways on flight #**** from Boston on November **, 2005. We apologize that the DIRECTV® programming was inoperable during your flight.
As a gesture of apology and goodwill, we have issued each customer on your flight a $5 JetBlue electronic voucher. When you are ready to use your voucher, please call 1-800-JETBLUE with your confirmation number ****** for this flight. The voucher is for you and is non-transferable. JetBlue vouchers are valid for one year, can be applied toward airfare on JetBlue Airways reservations only and are not redeemable online or towards JetBlue Getaways vacation packages.
We thank you for your understanding, and look forward to a future opportunity to welcome you aboard JetBlue Airways.
Sincerely,
JetBlue Airways
It was unprompted and quite surprising!

$5 isn't much, but If I do a BOS-JFK run anytime soon, I'll be able to get a 12.5% discount!
