Worst airports
1. London Heathrow
2. Paris CDG
3. Los Angeles - LAX Intl
4. Frankfurt International
For about two years now I have used CDG frequently between Bilbao and Aberdeen without the slightest problem. Admittedly this is only shorthaul but it does include going through Passport Control and a change of terminal.
For Passport Control there is an excellent fast lane for pax with short connections. I have never had to wait more than 5 minutes for an inter terminal bus and there is usually one waiting outside the arrival terminal.
Not one of my flights has been delayed nor have I had one lost luggage incident.
Guess I must be lucky eh?
