Even though most airlines allow you to choose you seat in advance, this seat exchange app allows you to make last minute changes. The yet to be launched app Sweatswappr is currently in beta and allows you to do away with assigned seating.
The app-based solution is supposed to reduce stress within the air travel industry. The peer to peer platform lets passengers switch seats prior to boarding the plane. Users can arrange a seat exchange directly while preferred spots, such as ones near the emergency exits, can be put up for sale.
This seat exchange smartphone application will be especially nice for travellers who are flying with budget airlines that don't offer seat selection. This affords them that small luxury at no extra cost.
