As you are in med school and I'm a few years out, here's my take.
-you'll make the $$ back over the course of your life, so eat the cost and charge the ticket. its definitely less stressful that way. seriously the stress might not be worth it.
or
-All AA right away as per millionmilers' note and cross your fingers.
-but as has been said already, dont spend too much more time hoping. if you can grab the flight that millionmiler mentions, take it.
good luck and let us know how you fare out.
