Effective August 8th Peninsula Airways, Inc. (PenAir), who had been providing daily flights to and from Portland, ceased service in Klamath Falls as a result of filing of Chapter 11 reorganization on August 7, 2017. This leaves the Crater Lake - Klamath Regional Airport (LMT) with no commercial flights at this time unfortunately. The Airport is diligently exploring all options for replacement service although the current industry conditions make this a challenging process.
