Apparently you can book on line, but I can recommend the personal touch via the telephone - the lady who booked my flights was extremely pleasant and can teach at least one of the UK's major carriers a thing or six about customer relations.
Well done Air Atlantique, damn shame Eurocrats seem to wish to curtail your professionalism.
Anyone booked for the 11am flight out of Biggin on May 24th, I'd be pleased to meet up for a drink in the Jail Inn afterwards.
