Received this email for a trip SEA-JFK tomorrow and didn't see it posted elsewhere so thought I would share.
To sum, if your flight is delayed 2 or more hours, you (and others on your itinerary) can receive a meal voucher and a free EMS seat... Doesn't seem like there is a restriction on flights delayed for weather, which is nice. This no-strings-attached trial benefit is unexpected and a nice touch.
Unfortunately I am already booked in Mint so that negates the potential benefit of the complimentary EMS seat. So in my case, ideally we are just on-time and that's that
EDIT: guess this is discussed (albeit slightly off-topic from the original thread) here:
Mosaic no more free even more space seats
Hello XXX,
Thanks for your continued business and loyalty to JetBlue.
It's peak travel season, and we wanted to give you a heads-up about a new benefit we're piloting for Mosaic customers and other travelers booked on your itinerary.
In the unlikely event that your JetBlue-operated flight tomorrow encounters a posted delay of two hours or more, you may opt to receive a same-day meal voucher* and an Even MoreŽ Space seat.** All you need to do is identify yourself to a JetBlue crewmember at the airport to receive this benefit.
Please note, this trial offer is only available for your flight tomorrow, and can only be fulfilled by a JetBlue crewmember at the airport.We look forward to welcoming you on board.
Yours Blue-ly,
Don Uselmann
Vice President, Loyalty
JetBlue
*Meal vouchers are subject to local airport concession availability.
**Even MoreŽ Space offer applies if not already seated in Even MoreŽ Space, and space permitting. Previously purchased Even MoreŽ Space seats will not be refunded.
