I have flown that flight previously (although it may have been an hour earlier) and it was a Thomas Cook branded aircraft. There was another airline (it may have been the one you mentioned), that flew out either earlier in the day or on the Friday - in addition to the more well known operators, such as TUI or Jet2.
