Flight canceled 2nd day in a row. This time they had a captain but no first officer. Gate agent announced that one was on the way but he didn’t know the ETA. After about 10 mins all crew leave the plane with bags in tow. Not a good sign. I politely asked the GA if they really had a first officer coming and, if so, didn’t someone know their ETA. His response was “tower knows but they won’t tell us until they’re sure”. Another 10 mins passes and flight canceled. I rebooked for the Sunday AM flight. Rebooking via the app is effective. Food in the lounges is pretty good. My only positives so far.
