Terrible. Do NOT use this app! Save your money and a lot of headache. They didn't inform us when they changed the flight, we weren't aware until we got to the airport and were told the flight has been rescheduled, to the day before.No customer service number, so we wasted time emailing . They didn't do anything for us, we had to find out own solutions. When we requested further follow up, they sent a generic email saying we should contact customer service. Truly horrible experience
