Just been able to buy 2x J class fares out of August from AMS for £1437 each.
Looked at UK prices for same dates and easily asking £1950 -£2300 for the dates i wanted.
Easy enough to buy a return to AMS and then connect with me EK flights still works out cheaper than the orginal 2 from the Uk ... ok it adds a couple extra hours in AMS but a big saving of £1100.
I've travelled to BKK many times but never found a flight at that cost and i used to then travel on my own........very happy with what i got....just rather annoyed about rip off UK fares
