With so many airlines offering one-way fares now, are there any disadvantages of booking this way using different airlines? I'm looking at booking a Jetblue non-stop flight one-way with return flights on Co (Boston-Cancun.)
The fare would be cheaper than booking CO roundtrip, the Jetblue flight is non-stop, and the arrival time back in Boston is much better on CO.
I only fly 3 or 4 times @ yr. so collecting points is not an issue with me.
