I just know a few...
A few days ago while I was at college I asked some German students about the word "Lufthansa" I told them I knew it was an airline but didn't know what was the meaning of the word, so they told me "Luft" means "Air" and "Hansa" means "Commerce" or "Trade".
She said to me it's more like:
"Lufthansa - Merchants of the Air"
SABENA - Societe Anonyme Belge d'Explotaition de la Navigation Aerienne.
IBERIA - There's no meaning for this word, Iberia was the first name of Spain. Now a days it refers to the Iberian peninsula where Spain is.
QANTAS - Queensland And Northern Territories Air Services
ANA, All Nippon Airways - In Japanese "Nippon" means "Japan". So it would be something like "All Japan Airways"
A few more:
AVIANCA - Aerovías Nacionales de Colombia
Something like: "Colombian National Airways"
LAN CHILE - Línea Aérea Nacional de Chile
"Chile's National Airline"
VARIG - Viaçao Aerea Rio Grande
"Río Grande Air Company"
VASP - Viaçao Aerea São Paulo
"São Paulo Air Company"
Could someone post the meaning for KLM?
