This app has gone from great to absolutely awful. First, it's impossible to get a hold of anyone in CS. Second, if you do get a response - be prepared to do all the work yourself (i.e. research airline policies, explain basic laws, etc). Not only did they keep insisting that my refund with an airline had expired (it did not), once they confirmed that I was able to use that refund to book new tickets - they stopped responding and are essentially holding my money hostage. Do not use this service.
