JetBlue has sent out an e-mail to Mosaic members letting them know that starting October 17th they will be switching to a group boarding process. Mosaic members will still receive priority boarding and this will be listed on their boarding pass. JetBlue previously boarded passengers based on their seat position (with the back boarding before the front). Mythbusters has an episode on plane boarding, airlines care a lot about boarding times because the longer boarding takes the more time the aircraft is sitting idle not earning revenue. As you can see in the Mythbusters episode some methods saved 10 minutes of boarding time compared to the front to back method.
It isn’t entirely clear how JetBlue plans to segregate the different boarding groups at this stage, if anybody has a JetBlue flight tomorrow please let us know how it goes in the comments below.
