Hi Majestyk,
Firstly, welcome to the site...[y]
The aircraft that serve the LGW routes have a lower capacity UC cabin and unfortunately don't have an IFBT working on board. (In-flight beauty therapist)
LAS is a very popular route. Lot's of people who visit V-Flyer travel via SFO for potentially a cheaper fare, better availability and use of the LHR Clubhouse. All LHR aircraft also have IFBT on board.
Enjoy your 1st trip in UC, I'm sure it will be amazing...
