Wow, I used to remember Pan Am too.. Anyway, I've never lost luggage with any of the airlines I've flown..
LanChile, AA, CO, Ecuatoriana, Saeta, Lacsa, Aerolineas Argentinas, Air France, Copa, US Air.
Sometimes my family members have complained about missing luggage when flying in Lacsa to Ecuador. And when I'm arriving in GYE airport, I hear a lot of complaints about CO misplacing their luggage. But I've never had a problem with CO.. I'm so glad !! Adios
