Seattle to Cabo San Lucas, Mexico from $222RT! (DIRECT)
Delta is going to war with their former partner Alaska and is putting Cabo on sale for last minute travel. Best dates are in March so if you're looking for a spring break, this is your chance! There are some sub-$300 fares from April to early June, also. This is a basic economy fare but it's international so a carry-on bag is included. You can upgrade for $5 each way for seat assignments but a checked bag is $25 each way. Use ITA Matrix Software to locate the best dates. Book direct through Delta.com for the frugal fares!
