Pros: Arrived early.

Cons: Waiting for the Jetway.

Pros: Off boarding was fine

Cons: So, Fort Lauderdale doesn’t have much Frontier service, so the desk is only manned about 90 minutes prior to boarding. No signs or indication of this means a lot of angry travelers standing inline for unknown amount of time. I’m sure the desk staff love everyone yelling at them. Dumb business model.

Cons: There was huge issues with our original plane and the lady at the desk was horrible with communication to all the passengers waiting for the flight updates. The one time I finally asked her if there was any updates, after almost 1.5 hours of delay and waiting, she took a very rude and snappy tone.

My flight from Chicago was delayed and nothing was done by the pilots to arrive on time. Despite the delay, I managed to arrive on time to my Connecting flight to CPH - only to realize that I was moved to a later flight. Now I have spent 2.300 USD on a poor flight that do NOT bring me to my destination on time. I am a frequent flyer, and will do everything I can Avoiding United going forward. Never United again

Cons: Not even a smile from the crew and no help when asked. I don't expect Asian-style grace and class from an American airline, but I do expect good old-fashioned American friendliness, and there wasn't even that. Also hate the all-darkened cabin in the daytime.

Pros: On time arrival is always appreciated.

Cons: Overhead compartment jammed with someone else's carry on. We paid for "comfort seating" and I frankly didn't see any difference - if there was more room on those seats, it was small enough I couldn't SEE it.
