JetBlue TrueBlue - Can a single award be used for 2 passengers?

If there are two seats on the outgoing flight available for reward redemption and none on the return flight, can I use a single award ticket to book 2 outgoing seats and then pay for the return tickets, or do both segments have to be used by the same passenger?

Yes you can . It is one of the nice things about the True Blue program.:)
