United Airlines flights from Phoenix Sky Harbor Intl Airport to Ho Chi Minh City (PHX - SGN)

This flight was a mess. For almost 6 hours, we were told conflicting information from the pilot, crew, members stationed at the gate and United members online and at the service desk. We had multiple technical difficulties that were communicated to us falsely or extremely late, leaving the passengers in a state of constant chaos. We boarded our flight after a heavy delay, then we were told by the pilot that we could not fly and deplaned. Dozens and dozens of people were sent across the entire gate to the customer service center that was no help for over an hour before finally telling us our flight was still leaving and stationed at a new gate. At this point, we were all unsure who to trust but went to the then empty gate, all very exhausted and frustrated. We finally left almost 2 hours later, arriving hours after our scheduled arrival. The first meal options contained both wheat, something I was unable to previously able to request special meals from the airline, and the ice cream was completely melted. Breakfast 6 hours later was also lackluster, containing only cookie briskets and a small Jogurt.
