Where did you find that table? There's loads of good stuff at
http://www.caa.co.uk/erg/erg_stats/s...ld=2003Annual, but I didn't see that one
Based on combining those in the top 50, the top 10 would read:
1 London Dublin 3,834,083
2 London Amsterdam 2,770,312
3 London Edinburgh 2,432,947
4 London Glasgow 2,186,304
5 Heathrow Paris 1,970,345
6 London Rome 1,712,151
8 Heathrow Frankfurt 1,459,163
9 Heathrow Manchester 1,385,320
10 Heathrow Chicago 1,356,051
11 Heathrow Los Angeles 1,180,145
A few comments:
1) Dublin is the busiest by quite a margin - LTN and LCY not included in these, but it is the only city to have 3 mentions in the top 50 - all LON airports
2) LTN does not get a single mention in this table - you can add a fair few EZ LTN pax to all of the top 5, exc DUB.
3) How many of LON/DUB or LON/AMS etc are transiting? I would imagine a good number from DUB transit in LON, whereas a fair few from LON transit at AMS, and vice versa?
