Following the demise of Pan American World Airways, Pan Am Express with its then 870 employees was purchased by Trans World Airlines for $28 million on 4 December 1991 and renamed Trans World Express (TWE), adopting RBD as new airline code. The European and Miami centered networks were subsequently discontinued, with John F. Kennedy International Airport becoming the sole hub for TWE. From there, 20 destinations throughout the northeastern US were served by 1993. By then, the airline had gotten rid of its Dash 7s, with the ATR 42 remaining the only aircraft type in the fleet.
