First time flying United Airlines... Ever.

A couple of things that I have noticed that are different than Southwest.

We had 4 flight attendants.
Our seating was predetermined.
The drink choices are better and they give you the whole can.
On this flight to Vegas the attendant sounded fed up with some passengers which was apparent over the intercom.
Better seats, more ergonomic.
They show an inflight show (an episode of the office) on the automated swing down LCD panels.
There are lavatories in the front and rear of plane.
No really bad seats.
The United terminal in Vegas was a lot 'cleaner' but that may be due to a remodel.
Overall seem less efficient than Southwest in checkin, flight service, baggage claim and being on time.
