I accidentally pushed the wrong date for my reservation, easy to do when you are checking multiple flights. I emailed and called right away. Within 15 minutes I got a call saying they would cancel my flights no problem. The guy also was kind enough to tell me that changing my flight to the correct date would actually be more money. I really appreciated his honesty. I didn't end up going with whatscheaper mostly because spirit airlines ends up charging a lot of money for bags, etc. But I will consider using them in the future.
