JetBlue introduces a five-month, unlimited companion pass
The biggest, and perhaps most exciting change, is that elites will receive an unlimited companion pass for every flight booked and flown between Jan. 1 and May 20, 2021. The companion doesn’t even have to be the same person on each flight, meaning that Mosaics can fly with one extra person on every flight, just for the cost of the taxes and fees.
Note that this limited-time benefit doesn’t apply to TrueBlue or Cash + Points redemptions only paid flights qualify for a free companion.
Additionally, both tickets need to be booked at the same time, in the same class of service and in the same reservation. Plus, the companion must travel on all the same segments as the sponsoring Mosaic. To book a companion fare, Mosaics should call the dedicated 1-800 number.
