Service monitors your travel as you fly, and files claims with airline(s) that delay or cancel your flight, without you having to do anything. We typically get users ~$600/year worth of vouchers or miles, all without them having to lift a finger. Just sync your inbox once, travel as you normally do, and know that Service has your back!
Usually you just have to just accept that your flight experience was poor. Now you can get compensated!
Pros:Extremely easy and automatic to get money back for flight interruptions. Well worth granting access to my email inbox.
Cons:Nothing I can think of.
