and, of course, you can still get CO miles on Frontier, even if the new program is an even better, shinier deal.

Frontier has been nothing but first-rate in my book. If that's discount, some "traditional" carriers need to take lessons. (They're also really darn nice, which helps a lot.) Hearing of the 33" pitch in the Airbuses (that's a weird-looking plural...) is very encouraging.

Now, say what you will about WN, but it has gotten me around dirt cheap before, and i hear promising things about JetBlue, but i've not as yet flown them, even if friends rave of 'em.
