Seattle to Puerto Vallarta, Mexico from $251RT (DIRECT)
Nice last minute codeshare deal from Delta and Aeromexico. This direct flight only has a few dates at the end of February and beginning of March at this price. More dates available throughout the spring but have a stopover in Mexico City. This is a Basic Economy fare so a normal sized carry on is included. A checked bag will run you another $32 each way.
