The SeaTac City Council voted to place an initiative on the November ballot that would raise the minimum wage in the city to $15 an hour.
KOMO reports it would apply to many hospitality and restaurant workers at Sea-Tac Airport.
If approved, the minimum wage would rise to more than $30,000 a year.
The SeaTac initiative is opposed by Alaska Airlines and the Washington Restaurant Association.
The state of Washington has one of the highest minimum wages in the nation at $9.19 an hour.
