Jetblue and United are teaming up. The airlines announced a partnership on Thursday to sell each other’s flights and link up their loyalty points programs. It’s the latest move by JetBlue to expand its network of routes. For years, Jetblue has been searching for the one — an airline to partner with, said Richard Aboulafia of AeroDynamic Advisory.

The airlines will allow passengers to use and collect points interchangeably and offer flights on one another’s websites and apps.

United Airlines and JetBlue Airways announced an agreement Thursday morning to share frequent flier benefits and sell tickets on each other’s websites.
