The next time you fly at BWI and you need a snack or a new book--don't waste your time walking.
You can now get what you want delivered right to your gate through a mobile app called Airport Sherpa.
Users can order food or retail items from vendors at the AIRMALL, and workers will bring it to them.
The service costs $4 to $8 per order depending on the distance between the gate and the vendor.
A similar app is set to roll out at San Diego International Airport
