Thanks for that, but MAN-HAM-MAN is coming out at over £230 return, which is more than double of what I have already paid for all 4 of the flights I previously listed and that price, unfortunatly, isn't possible for me right now.
I'll just have to hope this strike doesn't go ahead, or get a coach to London and book myself on the LTN-HAM flight as above.
Of course if I do that now and the strike doesn't go ahead it'll have been a waste of money for me, leave it any later and the flight and coach price will rocket.
