I have a crap ton of AA and DL miles and consistently for the last several years AA availability and mile cost/award is way way better than Delta 1 year away and 3-4 weeks away.

Got RT to SXM less than 30 days out for 15k and $80ish bucks a ticket on AA web special..

Never see DL anywhere close.

AAs issues are all labor driven. They got new planes, lots A320s. Times are good. But MX parrwork slowdowns causing ripple effects. Dont know much about their cause for why they have been doing it.

Luckily no issues on our flights this last trip.
