y...i thk OW is simpler in this structure, except for the fact the complication of AA/AC for domestic flights.

and *A is further complicated by SQ's snobishness...we wish we got SQ, sigh

anyway, good luck with the project!!!
too bad i haven't travelled too much on *A recently since i dropped by UA status. but if u need contributions on OW lounge after this project, i am glad to do so (i mistaken thot this was for OW, apologies)
