So I was pondering this question last night as I was trying to fall asleep. There are some airlines that I just don't know what they mean and was wondering if anyone knew off the top of their heads what they meant. And by meaning I mean their translated meaning. Like I know QANTAS means Queensland and Northern Territories Aerial Service but what about:

Lufthansa
Varig
Aer Lingus (what the heck is a Lingus?)

And is Air Tran short for "Air Transportation"? If so, what an ODD name for an airline

Anyway, just being curious is all.
