Checked my email this morning and noticed UA sent me 2 Waitlist notifications in the middle of the night. Got 2 segments confirmed in United Polaris first (ON) with miles and co-pay for a TATL business trip end of June/beginning of July. These segments were never offered for sale in Polaris first class (it was F0 A0 every time I checked), but the upgrade offer was available from the moment I booked the trip.
This will probably be the last time that I will experience the Global First legacy. I loved it and I'll miss it.
