Thank you and welcome all our OW Volunteer Ambassadors: thadocta, Dr HFH, DownUnderFlyer and squeeler.
Jerry a. laska & DownUnderFlyer,
Appreciate the info re my question #2 "Am I allowed to book an (one) AA codeshare flight that is NOT a trans-ocean flight, and NOT connecting to any AA flight?"
Jerry,
I’ve copied and pasted the fare code & reward mile charts per individual OW partners, and consolidatde them for fast reference. Thanks for the links.
I started that thread on a DONE4 (as provided by your link) some months ago, and the input from there plus further research and other factors prompted me to look at a DONE3 now (under separate thread).
