Horizon Air says it expects to resume its normal schedule Tuesday, after completing emergency inspections of 33 planes.
Hundreds of flights have been canceled since last week for inspection of the landing gear on the turboprop Bombardier (bom-BAR'-de-ay) Q400.
Horizon says it has not had problems like the landing gear failure that caused two accidents in Europe.
Horizon is running a letter today in newspapers in cities served by the airline apologizing for disruptions in travel plans.
The Seattle-based airline has a total of 74 aircraft in its fleet.
It serves 48 cities in the West.
