KAYAK’s top tips for finding a cheap flight from San Antonio to London

  • San Antonio International Airport (SAT) is the main international airport in the Greater San Antonio Area. Situated approximately 8 miles north of the city’s downtown area, this airport is a Merlin Airways and Avelo Airlines hub.
  • In London, you will arrive on your flight at Heathrow Airport (LHR), Gatwick Airport (LGW), or London City Airport (LCY). If you want to land at an airport close to London’s city center, you should book a flight that lands at LCY. On the other hand, if you want to travel affordably, check out the flights that land at LHR, as it serves a majority of the cheap flights that ply this route.
  • On your travel date, it’s essential that you arrive at SAT at least 2 hours prior to your departure time. Doing so will help you check in and complete the airport’s tedious security checks in time for your flight.
  • While waiting for your flight to London at SAT, you can relax in the airport’s USO lounge if you’re a serving member of the US military or an immediate family member of one. At this lounge, located near Terminal B’s baggage claim area, you’ll enjoy access to comfortable seating, snacks, beverages, magazines, and newspapers.
  • If you’d like to convert some of your cash before leaving LHR, you’ll be able to do so with ease, given that this airport features at least 25 Travelex booths. Spread across the airport, these booths are normally open from about 5 am to 10 pm. If you need help finding one, look for an airport ambassador. They are quite easy to spot, given that they all wear distinct purple shirts.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

Following a paid seat upgrade for enhanced comfort, I encountered an unacceptable odor in my assigned area. It took three hours for the crew to relocate me, and the replacement seat was unacceptably close to the lavatory, offering no improvement.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

I did not fly by vergin atlantic from bangalore to vasco da gama

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.
