Thank you aaron1262 and JetBlueFa, really appreciate your information.
Jetblue it will be
It sounds like a good way to go without the busy-ness of LAX and even SEA.
I do fly out of SEA frequently as fares out of SEA are often less then half the price then what we have to pay out of YVR.
IIRC Delta is using the A concourse also which I have used a couple of times to ATL.

JetBlueFa, when I took my booking to the part where you select seats the seatmap for the return was 3 - 3, that was for the evening departure out of Long Beach. Maybe there is an increase due to the summer month.

Either way I am happy as I have flown on both aircraft just different airlines.
Thanks again.
