Is the 60 day issue related to flexibility with aircraft changes on schedules?
Mrs TCAS is a very nervous passenger and still remembers Virgin's "we only fly with four engines". When trying to book to the Caribbean next April we found that one day a week there was a 747 operating rather than the b***dy awful A330. Booked the flights only to be told a month later that the return flight departure had changed. Went into the booking and found that they'd now also substituted a 330 for the 747, Mrs TCAS not impressed!
