All times shown on the BKA operating schedule are departure times. In order to maintain on time service, we ask that all passengers be present at the service locations at least 10-15 minutes earlier for ticketing and boarding. Once all scheduled/reserved passengers are boarded, the driver is then free to depart the service location. Since all departures from SeaTac are on a walk-on basis, exceptions can be made at the airport. This action is necessary as a hedge against the expected high traffic in Tacoma and on I-5. In spite of the rising cost of gasoline, traffic on all roadways remains at record levels and has resulted in incidents of speeding, reckless driving and accidents and thereby causing further delays!
