Q – I know the airlines can notify you of an assigned gate or change, but is there any single source I can use all of the time to get information without having to trust my airline to update me?
A – There are two apps that are quite good and both have a basic version free. Try Iflyairportguide or gateguru. They will give you security checkpoint times as well as gate assignment at all major domestic and hundreds of airports around the world. If you fly frequently, we would recommend the “Pro” version.
