Pros: The planes are nice and new. Prices are very cheap. If you book economy and then upgrade to "extra room" seats and buy a meal seats you're basically flying in what they call businiess class for a lot less.

Cons: There was a huge snowstorm in Boston. A lot of people did not make it to the airport before the check-in desk closed. The airplane itself was grounded because of the snow for two hours. So a lot of people were in the main waiting area, while their plane was at the gate, but WOW did not care at all. They would not bring any gate agents out to check people in even though the plane was on the ground waiting. Many of us tried calling their support line - no answer. After a very long wait you get to what sounds like an India or Pakistan call center. The people there don't have any information, and the only things they can do are whatever you can do on the website. WOW has no real phone agents. I saw their gate agents later walking around and asked them to check us in - they shrugged. Would not check us in, despite the plane being on the ground. They could care less. Other airlines were shocked at how we were treated. Iceland Air was amazing. They saw our predicament and brought one of their managers out to their check-in gate to sell us last minute tickets on Iceland Air. A bunch of WOW customers ended up getting tickets on Iceland Air, and we actually ended up flying out of Boston before the delayed WOW air flight. If you get on the WOW flight - service is good. But you're taking a risk. Ground staff really does not care at all and will pretend they don't know you.

Pros: This was a cut-price flight. Considering what we paid, the flight was amazing value for money. The plane was new. There was plenty of overhead space. The seat pitch was adequate. We took our own food. We slept for most of the flight. We arrived on time. If Norwegian can continue to keep the price low, I'll happily choose to fly with them again.

Cons: A free soft drink and nibbles would have been nice, though hardly necessary.
