Kind of an odd situation -- I need to fly DCA-NYC tomorrow (to catch a 6:30pm JFK-SFO) and couldn't buy my ticket until today because of uncertain scheduling tomorrow in DC.

There is a 1:10 p.m. DCA-JFK that is a little too tight but I can make it if I have to. There is a 2:59 p.m. (AA5444) that is showing cancelled (PSA CR7). Apparently in its place is AA9387, also at 2:59 p.m., on a Republic E175. ExpertFlyer shows plenty of availability on AA9387 but it does not appear to be for sale on AA.com or the regular channels.

I called AA and the agent was unable to see AA9387 until I gave her the flight number. I asked if I could buy a ticket and she wasn't sure. I then did an EF search and saw "T" availability so I asked if she could book me an award seat -- and she said yes! So I went ahead and ticketed that for 7500 miles (-750 Citi CC rebate). I received the email confirmation with ticket # and have since cleared the upgrade into the only remaining first class seat. So, all is good.

But is there anything I should be worried about? Isn't it strange that AA wouldn't sell seats on this flight that appears to have Y7+ availability when the 1:10 p.m. flight is down to Y2 (and was Y0 earlier)? Why won't the seat map come up on EF? (I can only see the FC seat map on the AA app, and I didn't have the chance to look at it when I was still in coach.) My concerns are that the flight doesn't really exist, or will somehow disappear, and then I'll miss my 6:30 p.m. JFK-SFO. I am hopeful that these are irrational concerns and that someone will set me straight. Thanks in advance.
