Having done my INN historic routes post you can see in Winter 2011 the B752 was used on 2 flights a week from LGW,
I’m not sure about Manchester or Birmingham (I believe Manchester may have been a 757 route in the 2000s but I was unable to find anything through the wayback machine) but for an irl route which Jet2 is on, itself having never used 757’s on the route, it really would be great to see.
