What happens if a flight gets cancelled and you purchased the "Wanna Get Away" fare? Do they get you on another flight for free or do you have to pay for another flight? I've never had that happen and was just wondering how it works.
Go to the section titled "Irregular Operations" and it covers this.
Basically you can book for no additional fee on any other flight with room in the 14 day period around your flight, or have your money refunded to your credit card.
I'm not sure if the refund is the case for weather delays.. but it's all in that document.
