Friday, I booked LAX HSV in November. I chose DL 1212 at 0600 JUST because it was a 764 with a better upgrade chance (20 of 36 seats available on seat map) and seatback video. Today, it is now a 763. If I wanted to fly on a 763, I could have taken either the 0715 or 0830 flights and gotten some sleep. I just tried calling DL to see if they would switch me for free to the CVG flight where I could use a PMU; no luck.

I guess I should have taken the CVG flight originally.

I have been out of the country for a couple of years so I haven't had to worry about domestic upgrades. I really thought that SMS (actually international desk) would make the change. Hopefully, the times will change by a minute or two so I can give it another try.

Sending an email to SMS via delta.com sure works great. Ten minutes after I sent in my request, I received a positive response.

Thanks Delta! :-)
