TF-ELA is not a MAN
based aircraft - or if it is, it hasn't been seen here for ages! As for based aircraft, it really does tend to change an awful lot these days. The list above is pretty accurate, except we really only have one 757, G-LSAD, which is white with full Jet2 c/s. The others are usually rotated.
As for the 737s, other common frames at MAN
are G-CELH and G-CELZ (still in old c/s - silver tail with the '2' in white). Don't also forget G-FLTC, Flightline 146 leased by Jet2.
On a further note, G-CELR is also a regular visitor, although it is currently operated by FlyGlobespan in their c/s.
