Why Does the US Postal Service Owe This Small Maine Airline $400,000?

According to an article in the Portland Press Herald, a Maine island air service says it will restart mail delivery on Wednesday after briefly pausing service to highlight nearly $400,000 it says it is owed by the U.S. Postal Service.

In a social media post Tuesday morning, Penobscot Island Air announced it would not deliver USPS mail for the day, explaining it needed to take a brief stand due to not receiving payment since mid-March.

By Tuesday night, the company said that move appeared to work.

In an update posted around 8:45 p.m., Penobscot Island Air said deliveries would resume Wednesday, adding that USPS had agreed to pay roughly 25% of the nearly $388,000 owed by the end of the week. The company credited its contract officer with securing the progress, noting that such movement is unusually fast for the agency.

The small airline, which is based at Knox County Regional Airport in Owls Head, does not just provide mail delivery.  They also fly freight and passengers to the islands.  The flying service also offers scenic tours.  You can learn more and check out their pricing HERE.

Penobscot Island Air also expressed appreciation for public support and Maine’s four members of Congress, saying the delegation is pursuing a congressional inquiry aimed at helping the company recover the full amount owed.

The company further thanked Maine media outlets for bringing attention to the issue, acknowledging it had been trying to resolve the situation on its own for too long and should have reached out to the community sooner.

In its update Tuesday night, the company said it believes the situation reflects the system functioning as intended.

Earlier Tuesday, Penobscot Island Air said it had transported mail on 75 days so far in 2026 without receiving payment for any of those deliveries. Prior to the evening update, a USPS regional spokesperson said in an email that the agency does not publicly comment on details of its business relationships, but confirmed it would contact the air service to work toward a resolution.

The company said it had already made repeated attempts to address the issue directly with USPS without success.

In its earlier statement, Penobscot Island Air said it had spent significant time trying to resolve the matter through meetings with USPS financial officials and local representatives in Rockland, including frequent calls and in-person visits in an effort to get the necessary paperwork completed.

The company emphasized it understands how important reliable mail service is for island residents and said it never intended for the disruption to last, adding it was prepared to resume deliveries even without payment if necessary. It also noted that FedEx and UPS deliveries continued uninterrupted on Tuesday.

Penobscot Island Air added that while its mission is to serve island communities, its employees still rely on consistent pay, and the business cannot operate if a significant portion of its annual revenue remains tied up in federal bureaucracy.

The company said it informed local leaders and island postmasters of the decision on Monday, adding that those officials were supportive and willing to help elevate the issue.
