My personal opinion - I dislike them.
Be it leases to TOM or LS; at least give them titles as clue to who they are operating for. Even buses must show the legal operator and registered operating address so why should summer leases be different? A red “TUI smile” or Jet2,com would at least give a clue to which aircraft is operating for whom. It would also give the flying public more confidence on which aircraft they are flying on.
Meantime nondescript white titleless 320, 737 and 332 ply the European skies.
White tails
Re: White tails
Agree, grinds my gears too for some strange reason. I would imagine the costs involved even for a basic livery might prove too much depending on the length of the lease. But I agree, there should be at least an ident on the tails of some sorts.
