MD-83 Portland to Las Vegas at 9000 feet?


Allegiant MD-83 PDX to LAS flies the entire route at 9000 feet. It caught my curiosity as it flew over my home Sunday, April 8. Can anyone shed some light on this one for me? Thanks!


Probably a pressurization issue, sending it to their maintenance facility.

The 9 prefix to the flight number indicates it was a non-revenue flight, and I’m guessing the 409 refers to N409NV.

Probably a pressurization problem being ferried to LAS for fixing.

Ah, pipped to the post again !


Thank you! Makes perfect sense now.
