Hi all

Will be flying from Singapore to Dublin with Singapore Airlines and I have a few layover options.

What I'm after is which is the easiest airport to get through. Choices are Heathrow, Manchester, Amsterdam, CDG and Munich. Heathrow has the shortest layover and the other four are between 3 to 5 hours.

A few people recommended Heathrow but I thought this was a nightmare airport to go through?

Does anyone have a preference or airports to avoid?
