I have a segment currently booked on USDM in QR J from DOH-LHR, and while checking routes on KVS tonight, noticed an opening in QR F.

Is it worth $150 to upgrade to QR F? The food differences seem slight, and the only other difference I can think of is that QR F offers private BMW transfers. Anything else?

I'm currently scheduled to fly on the all-J A319, which also looks like a very nice experience.

On the other hand, the flight isn't until Feb '15 and according to the schedule, may be on the new A380, in which case the $150 is a no-brainer. But given the repeated A380 delays, I'm not sure I can count on being able to try the new A380.

Thanks!
