I tried to used this for a flight booked a month in advance and found it to be basically useless. The policy for freezing or getting alerts is nuanced and hard to come to terms with, unless you just click through and end up here posting a 1 star review bc they took your money without being clear. Even if I don't get the absolute best price I'm not going to continually waste time and money trying to use this app when I can just set an alert from other apps (kayak as example) and see the price.
