Since it's close to on topic, I'll take the opportunity to mention that I no longer buy round trip tickets. It used to be that round trip offered a discount over one-way each way, but that no longer seems to be true.

By booking one-way, I can fly different airlines if I want, use miles to "buy" two tickets one way and cash for two tickets the opposite way rather than one FF ticket and one cash ticket round trip, and I can buy each leg on a different day dependent on price.
