I'm fairly new to flyer talk and have become quite addicted. I've been reading with interest a lot of the reports. I'm very puzzled why Ex-EU flights are much cheaper when they are obviously having to travel further. I'm looking at flights in J from GLA-SFO then LAX-GLA in May in J, and it's coming in over 3000GBP. If i was to fly AMS-SFO then LAX-AMS, it's only around 1800GBP. Why on earth is this?
