Natrona County International Airport, Natrona County, Wyoming, has partnered with COPD LLC to offer oxygen concentrators to passengers with medical oxygen needs.

Larger planes that fly out of larger airports usually offer medical oxygen, but many small planes often do not come equipped with medical oxygen supplies. Because of this, those with medical oxygen needs often find it difficult to fly out of airports like Natrona County.

When this problem was brought to the attention airport managers, they used the airport’s operating budget to purchased three oxygen concentrators for $2,300 each from COPD LLC.

Now, travelers can sign some paperwork and deposit $500—refundable upon the machine’s safe return—to use one of the oxygen concentrators for their flight out of Casper.
