Southwest Airlines

Los Angeles-Las Vegas. Booking was simple, efficient. Changing booking to later flight for small additional charge was also simple and efficient. Check-in easy and quick. Flight was delayed by around 1 hour which was mildly annoying but not uncommon in this day and age. Boarding was in groups. No priority given to families with small children/infants which is probably a mistake; upon being refused pre-boarding a mother with infant was told to "go fly someone else" if she didn't approve. Not a professional attitude. Onboard service generally good. Prior to landing, a passenger opposite was allowed to continue lying horizontally across 3 seats. It wasn't clear whether his seatbelt was fitted, however in the UK this would not be permitted. Flightcrew switched off seatbelt signs whilst aircraft was still taxiing at considerable speed toward its gate in Las Vegas. This seemed a little premature and would be a breach of safety regulations in the UK. Experience overall was average, but I have concerns regarding Southwest crews' attitude to safety procedures after this flight.
