Pros: We made it safely

Cons: Awful experience. Early in the day I received several updates about my flight being delayed. No details on why, but much appreciated. Upon arriving to the airport the flight was still showing 59 mins delayed. Oddly, with all of the early communxaruin, it suddenly ceased! No communication for at least 2 hrs before the flight. Even as the 'would be' boarding window, the line formed with people asking questions... yet there were no answers or updates to the proposed time of departure. Even when the 59 min late departure came and went, there was NO communication. Folks were in an uproar! Finally, with no announcement, the gate attendant just started checking boarding passes and letting people go through the gate. Huh? I have zone 1, yet he said, we're just boarding everybody.... and, on the 3+ hr flight, only 1 bathroom worked. AWFUL EXPERIENCE!!!
