Briefing

What Hype is tracking

  • AEI has launched the first Boeing 737-900ER passenger-to-freighter conversion, the 737-900ERSF, with development expected to take about four years.
  • The announcement extends a broader narrowbody freighter pipeline and recent 737 conversion activity across the market, including operators and converters preparing 737NG freighters (see a recent example of a 737-800 passenger-to-freighter preparation and 737-800 freighter additions: https://hype.aero/?story=26654c99-62e7-4936-97c8-c8eb9496fc3e and https://hype.aero/?story=376d9488-d4da-42f4-a8c9-e605ceeeaafd).
  • The 737-900ER remains an active type in commercial plans — Sun Country is set to introduce the 737-900ER into service in late Q3 2025 — providing immediate context for operator interest in the -900ER family: https://hype.aero/?story=365fdcd6-277d-473c-94e5-166cedc99380.
