Ye paul im gonna try see how it works from LHR DIrect to Dallas aswell, just seen that one.. Im gettin these from expedia.com by the way, brilliant site , shows all options for your flight destinations that u want.
But ye, if i dont find anything more appealing i wont hesitate goin for the one i noted already.
ANd yes, goin a day early just to have rest and be ready for it all, as i dunno if ill be able to sleep on the plane for long.
And plus the arrival time for the 21st was like 10pm is quite late so ye. All the better goin a day early, knocks a day off my countdown!
