It was operating for Austrian Airlines but it would seem (looking at Alastair T. Gardiner's photo taken 2 days previously) that the Austrian titles were only on the port side of the aircraft (i.e. the passenger entry side).
In the early nineties Fokker built 'white tails', aircraft that had not yet been sold. PH-LXT was finished in spring 1993 and went into storage at Woensdrecht. It was not until March 1995 that it became G-UKTI with Air UK. Here it is in cocooned state.
