CO 752 LAX-EWR is by far and away the best.
757-200 plane type.
how is the 757-200 lax-jfk on united?
Not lie-flat.
IIRC lie-flat for EWR-LAX isn't guaranteed.
If your 50k is with US Air, then they charge the same price, 50k, for biz and first, so you can book United PS First Class. It's a more expensive ticket than the CO 752 and it flies to/from JFK but is not really a true lie flat. Pretty wierd quirk in the US Air award chart though.http://www.usairways.com/pv_obj_cache/pv_obj_id_E2BFEDE552D8CD3D20C8AA9099F7090B578C0000/filename/partnerawardtravel.pdf
Dates?
is that 50k for first class on a 3 class plane?
Does the American airlines Boeing 767-200/200ER from JFK-MIA have lie flat seats in first?
seatguru seams to think that they dohttp://www.seatguru.com/airlines/American_Airlines/American_Airlines_Boeing_767-200.php
If you are on a CO 752 it will be lie-flat.
