Delta Airlines has filed a notice saying it can no longer provide service at the International Falls Airport without government help.
The airline, which merged with Norwest Airlines last fall, filed a notice with the U-S Department of Transportation to discontinue service because it is no longer financially self sustaining.
The move is considered a formality for the airline to be able to apply for money under the essential air service program.
A decision on the subsidy is expected in the next 90 days.
