In reply to ByEek:
> I lot of people saying 3 hours. Whenever I have been told 3 hours I have ended up getting through all the faff in 30 minutes and then having to kick around for 2.5 hours. I guess there are forces at play that think you are going to spend lots of money in that time. It is certainly overkill if the connecting flight is only 30 minutes long. My mate did a connection from Gatwick to Heathrow in two hours the other year despite the M25 being completely blocked. It can be done!
It can, but you have to factor in delays out of your control...
I have been extremely quick through airports, and extremely slow too, especially if bags have gone missing.
My choice would be to fly directly into regional airport if possible or overland journey, again if possible.
These days the least number of flights and stops I find results in the least amount of stress.
Recently travelled CHC>SYD>BKK>DUB>MAN and return having to go through security checks at all of them despite only technically changing planes once. NOT pleasant.
