I met a lovely lady who had flown a group of enthisiasts last winter out to Friedrichshafen for the day in a 757. I think she said the flight was full, or pretty close.
Where could you take well over 300 A300 fans for the day and keep them all happy - Whipsnade Zoo!
Monarch seem to have missed a 'trick' it would seem! A 'Buster Bus Day!'.
