thanks so far for your answers!
ive been doing some research today on the net lol, and so i will share it for those of you who may also be in same position as me
ive come to a conclusion that if have an early check in for a lgw flight, the night before i could either :
1) drive down, park at lgw. I think a 4 hour drive home after a 10 hr flight is not appealing nor safe!
2) i could get the train, well 3 trains! my journey would be liverpool - london euston - london victoria - gatwick airport, taking around 4 hours. same on way back. This is probably cheapest option
3) drive to MAN, park car and fly down with BA, this being most expensive option at around £75 but the quickest
And for LHR:
1) get train from liverpool to watford junction then heathrow express coach to airport, approx 3-4hrs journey time
2) fly down with BA or BMI again costing £75 approx
Whatever journey i take i would have to stay at Travelodge/Ibis etc, ive heard that if you are BA or virgin staff thye give u a good rate, is this true?
any more commuters comments would be EXTREMELY helpful!!!!
