I guess the better question is, since most of the other airlines don't have lay flat seats (angle only), between American and US air, which one generally delivers better service and seats?

Here are some schedules and the aircraft type for the outbound. All inbounds are the same back to PBI:
Inbounds for all returns:
YVR-DFW 738
DFW-PBI 738

Outbounds:

1.
AA PBI-DFW 738
AA DFW-LAX 763
AA LAX-HNL 32B

2.
US AIR PBI-PHL 319
US AIR PHL-DFW 319
AA DFW-HNL 763

3.
US AIR PBI-DCA 319
AA DCA-DFW 738
AA DFW-HNL 763

4.
US AIR PBI-PHL 319
US AIR PHL-LAX 321
AA LAX-HNL 32B

For you experts, which plane schedule do you think would be better? I appreciate your thoughts as I wouldn't have any clue beside looking at seatguru.
