They'll want airline pilots to be licensed. 

My question is if its ok to do it for airlines, why not housing?

The airlines are a completely different situation. 

Unfortunately, 'no shows' are common everywhere - restaurants, airlines, weddings/parties, and yes, real estate. 

I don't intend to shop more than I have to, and opening new credit cards has allowed me to rack up huge amounts of various hotel points, airline miles, and credit card points in a much shorter time than it would take if I just spent on the same cards regularly.

I heard recently about someone in Houston who is making great money renting exclusively to airline attendants who share rooms.

You can also get a Chase Saphire card for personal, combine points in the two cards, and then transfer to hotels or airlines.

In the last couple of years, most of the airlines and hotels have devalued their loyalty programs, making such insane award redemptions even more difficult.

I will not fly this airline ever again.

Of all the pilots I meet on here, I don't usually meet airline pilots.
