Which 788s are short haul configured?
TUIB/H/I Were I believe the reconfigured ones, but can't be 100% accurate, as may they have changed.
I was just wondering if the individual 757's follow a set of routes like the 767's do
It's not so much that a particular registration only operates to a particular schedule, but is more coincidence if it is operating the same schedule each week. The planned schedule is usually set by an aircraft
type to be used for the duration of a season and not a particular frame. It is more common to see the same registration showing up at certain destinations with the 767 routes as there are now only 4 left in the fleet unfortunately. Aircraft also swap around bases (often down route) usually for maintenance reasons. Three of the 767 aircraft are currently based in MAN with the other at LGW. Hope that helps.
