I have actually been EUA'd on all legs now except PHX-DTW. DTW-PHX (yes, silver with meal) EUA'd last night.
I went ahead and checked in at 23:59. however, i think i may have screwed up. I clicked yes for the upgrade. it told me no, and that i was on the SB list. but i did not check in. i checked the stsanby list, though and it said i was listed.
I ended up checking in and printing a few hours later.
I have 16A on the 757, so its not that bad.
I am still shocked that a 7am sat flight is so full.
