Thanks for all the advise. Pretty sure that this EasyJet connection through Bristol is a non flyer, so I've started booking KLM; NCL through AMS onto CPH. A bit expensive unless you book well in advance.
Got delayed (EJ yet again) last week, so really need to start considering other options. Problem is EJ are a "Point to Point" carrier (their words) and so don't give a "flying f**k" about connecting flights / trains (my words).
I'll not fly with BA unless I have no other option, as I hate them. Was an IT contractor for them a few years back and they treated us very badly. Found it funny when all their IT broke - unlucky.
