April 24th, 2014 at 17:36ZSouthwest Flightplans: The Southwest Airlines (SWA) flightplan format is now available for use! Southwest uses a Jepp Plan OFP followed by a custom WSI weather briefing, both of which have been reproduced as accurately as possible.
March 20th, 2014 at 03:20ZJetBlue Flightplans: As of a few days ago, the JetBlue (JBU) flightplan format is now available for use. This format features a new "TLR" (Takeoff and Landing Report) feature, which gives runway analysis and performance information such as Max Runway Takeoff Weights, V-speeds, Required Landing Distances, and more! Not all formats include TLRs in the real world, and therefore "JBU" and "JZA" are the only SimBrief formats to include TLRs at this time.
