Someone said it before....Signature is like all the other companies who have decided they only want high rollers in their doors.
The good news - if you have money and aren't really watching the bottom line, they will dote on you like you wouldn't believe. Pump 100 gallons of Jet-A in the tanks at $3.00/gal and they are your best friends. Need a hotel, need a car, have some popcorn, get yourself a latte......heck, they'll even smile at you.
Buy the minimum or try to get fees waived and now your second class dirt. And please, if you must fly something without jet engines on it, keep those natsy props as far away from the building as possible. The front door and red carpet are for our premier guests. Eliteism at its finest.
So for the pilot who drives his Ford Escort to the parking lot so that he can get in an $18M bizjet paid for by Megabucks Corporation, Signature looks like walking in the front door of the Country Club. Just remember, you are the hired help. The marble and glitz is for the customers. If they keep your customers happy, then you're happy. If you want, you can roll up in your Bonanza, pay them $200 to use the ramp and they will smile and give you the same treatment.
I used to have an American Express gold card in my past life, same deal. I used to go to daily fee golf courses and blow $100-150 for an 18 hole romp - they smiled at me the same way. I used to own a brand new Lexus - same smiles at the dealership. Now I fly for a regional, drive a Corolla, play public courses and what's a credit card? PS. When I'm flying my small avgas burner, I use Airnav and find the cheapest fuel prices - that's who gets my dollars.
