Note that Fly Sharp is a trading name of Southall Travel. Would never ever use them again. Dreadful experience. Booked a "flexible" ticket depending on Covid restrictions and when Singapore stopped UK visitors in January 21, Singapore Airlines put a message on their webpage that everyone was entitled to a full refund whereas Fly Sharp wanted to charge me a £400 fee for cancelling which meant I would have less than £100 refund. They said I wasn't entitled to a refund and Singapore Airlines said that I was and to go back to them. It just went round in circles for weeks and it was extremely frustrating that an organisation could act in this way. Fly Sharp just tells lies and don't call the airline at all. SA were writing notes on my booking and FS were saying there were no notes - then SA saying they can see they that FS had not called at all. This happened several times. At one point the Fly Sharp telephone number didn't even connect so I found another number and the operator answered "Southall Travel". When I asked if they were Fly Sharp she didn't answer and just asked me what the problem was. So take note that they are one and the same! Anyway, thank you to Singapore Airlines for intervening and I eventually got a 100% refund :)
