I am a former AA Executive Platinum and CO Gold elite. I fly jetBlue as exclusively as possible, whether for short flights or transcon, and about 90% of the time on business.

Actually, I find that jetBlue is a much better airline for a business traveler on a budget than any of the legacies. Why?

First, because an affordable ticket can be purchased at the last minute, unlike most legacies, which will charge you an arm and a leg, an arm and a leg that will most likely land you in a middle seat of a much less comfortable economy section.

Also, when you buy one of these last-minute, more expensive tickets on jetBlue, you will be guaranteed an aisle or window seat in the 36" seat pitch section of the plane.

I save my small business lots of money and I always get a comfortable seat.

That's a lot better to me than spending two or three times as much money and having only a small chance at an upgrade on a carrier like CO.
