Eastern routinely lease their aircraft to other carriers for extended periods, in recent years that has included TAP, Aurigny - which didn’t go well and was terminated early - and KLM now I believe. Hence the unusual link for this weekend’s football charter from MAN.
Eurodirect operated a BOH/AMS and BOH/BRU schedule for a couple of seasons, I used it several times, always a Jetstream 31. They also served CDG, which I also used several times on the ATP.
TUI operated a BOH/AMS schedule in 2005/6 I think, with the B733, I also used that a few times, on one occasion I flew on a TUI B757 BOH-AMS which replaced a tech 733.
An AMS service from BOH is now highly unlikely, due slot limits at Schiphol, in my view this destination will remain the jewel established in Southampton’s crown.
