Some of them exist as direct flights, but only within a range of dates. Most of the ones to the Caribbean only book into 'D' class instead of 'A', for those on AONE RTWs.

but with the new 1.5 q-pts for D class in AA's FF program, that is not a major concern. true, that the class of service bonus will be 25% instead of 50%, but most of these flight are relatively short. for most of us, the q-pts are more important for keeping OW status
