I have been monitoring today's CO 1726 EWR-SAN as that is the flight my wife is on tomorrow with an $1,800 H ticket. That flight is now A2 F0 and she has NOT ben EUAed.
FOR TODAY: 3/19

3/18 10 PM A4 F1 ???????
3/19 6 AM A2 F1 ???????
8:40AM A2 F2 This is the 3.5 hour dump at 3.5 hours before 12:10 scheduled dep.
Note that it remained A2 F2 until 11:50 (20 mins before flight time). You mean that there were no silvers or companions?????
11:50AM A4 F4
12:10 Departure A0 F0

It kind of makes you want to scratch your head.
