It is actually interesting that they do not require r/t purchase on these deals. It has been a while since I've seen a sale on CO that didn't require such.
Good point! LOL
Many Mexico fares, are one-way fares. There is a bit of a tax break to booking both directions on one ticket, but the fares themselves are often times one way fares.
When I search for Mexico trips, I sometimes find the best deals are on a mix of carriers (one carrier out, another back).
