they can get US by the b_lls if they can succeed in pricing out JFK-CLT properly. If they can swing $69-79 each way, they can compeete w/ US. I cant count the times for business Ive flown LGA-CLT on a Tues-Wed trip and paid $600 on US. If jetblue is offered for $200 RT, Id much prefer Jetblue. I mean its a measly 500 miles wahcway on US anyway--i'd rather fly in comfort and style and watch some CNBC on the way down....Its debatable whether the 4-8 TB ptsmight be of the same vakue as the 1000 miles ....(not talking about CP bonuses etc)
The more flight options out of JFK, the better!
