Here in Portugal, we have still 3 operating L1011s.
One with YES linhas aereas charter (CS-TMX
, ex-Delta), another with LK/Luzair (CS-TMP
) and finally one (CS-TEB) with MMZ.
They are used for wet leases and operate charters for their companies on the routes to Brazil, Cuba and Punta Cana. Try the following websites and contact the respective owners for a vacation where the L1011 is used. Not every holiday package of them is flown the L1011, but you might try asking especifically for this aircraft.
Regards, and good luck.
