Oh
airlines 
Some years ago I had a friend visiting from NZ, we were both on motorcycles (I keep a "spare" for visiting friends). We'd been in Boston, and noticed one of the tires was down. We stopped at a gas station. He asked where the airline was - and got directions to Logan airport from the attendant. We got the right information when I asked for the air
hose.
As a BTW, I've noticed that pneumatic fittings tend to have proportionally smaller IDs than ones for water. No idea about these particular ones...
