As a CO Platinum, I was scheduled on an H fare EWR-LAX next Tues 3/26 returning 3/28 with seats in coach. (As usual ITN was showing F0 with A9 D1 etc on both fights.) This morning I checked my CO itinenary page and saw I now had FC seats in both directions--no EUA notification, and ITN was still showing the same data. I called OP to double check, and they said, Yes, I had been upgraded!! Not sure from where or why and since I'm not one to 'look a gift horse in the mouth', I just said thanks and hung up.
Anyone else experience this type of upgrade??
PS--my flights were the 4:00 pm out of EWR and returning on the 7:00 am from LAX--perhaps that had something to do with it???
