Edinburgh

I’m planning a vacation for January of 2009, and I’m concerned that all of the new FAA regulations being imposed on the airlines and all of these flight cancellations combined with high fuel costs are going to make airfare go up over the next few months. Originally I was going to wait until closer to my vacation to buy airfare, but now I’m afraid if I wait too long, airfare will skyrocket. Anyone have an opinion on when would be the best time for me to buy my tickets?

to the nearest 25 mils, how far would a london bus travel on a full tank of petrol while driving around the city at an average of 30mph?

I’m planning to travel around UK in July for 3 weeks, big cities in general. I’m not sure to choose among Britrail Flexipass (with I’d have to buy before going there), trains paid in the moment or buses.

Which is the best cost-benefit one? Thanks.
