Easyjet do a Bristol - Amsterdam flight for 拢50 one way on 18th Sept.



KLM do Cardiff or Bristol - Amsterdam but it's 拢300

KLM also do London City - Rotterdam for 拢100



Is there any chance you get get a bus or train to london or birmingham and get a flight from there. you'll have a lot more options that way and it's only a few hrs.
travelocity.com. Hopefully you can find a cheap flight still at this time. I usually book 2-3mths in advance. Way cheaper.How/where can I get cheap flights?
