Previous identity EC-ETB of Futura, leased by AB Airlines for the summer of 1998. Confusingly, on this day, it was operating a Futura flight!

This 737 was registered to AB Airlines from 29th April 1998 until 2nd November 1998 and operated on behalf of Futura during this time.

This registration was applied in 1998 to this aircraft, that was the first to join Futura's fleet in 1989 as EC-401.
