It’s been noted in the past that not every $69 flight is worth it. Sometimes, they actually end up more expensive than if you had booked with a more traditional airline. But today, one of the few opportunities to get a real deal is back: Wow Air is offering $69 one-way flights to Iceland. That means round-trip fares as low as $200—nearly 50 percent off the usual cost.

Before you agree to an all-inclusive deal that covers meal plans, you should do some research about dining options in area adjacent to the hotel or resort. In a place like Cabo San Lucas, Mexico, there are scores of good restaurants in a relatively small geographic area. You might miss out on some excellent dining opportunities by signing up for meal plans that send you to the same place every day.
