However, WOW is a budget airline, so don't expect to be treated like royalty. With each ticket purchased at the cheapest ticket tier, you get to bring one personal item. A carry-on bag will cost $39.99, and a piece of checked luggage costs $10 more.
Despite the caveat on WOW's fees, there are plenty of ways to get a cheap trip out of this sale if you're willing to dig around a bit. Though, you should probably hurry because the cheapest flights aren't going to last long, even though the code is valid until August 27.
