At the moment, JetBlue flies from Charlotte direct to Boston and New York/JFK.. Which is fine if you're going to one of those cities, but if you're flying south or west, it's a bit out of the way.
They operate one gate at CLT, A4. Plenty of seating and there is the airport's free wifi.
All of the flights to and from Charlotte are operated on Embraer 190's. These are regional jets so the overhead bins aren't as big as you might expect on the bigger planes.
Everyone I spoke to was more than pleasant. This is a business that is focused on customer service.
If they'd add some more destinations from CLT, that would be awesome. Until then, I'll probably be on Delta unless I need to go to BOS or JFK.
