My eldest sister booked a holiday to Spain in 1968, the carrier was Autair and much was made in the brochure of the new BAC 1-11s for that year.
Just before she left for her holiday my father (flight shed inspector at Hurn), told her that the first 1-11 had not been delivered yet so the flight would be on something older.
She flew out on a Constellation. The return was on the newly delivered 1-11.
How much would you pay to do that today?
