How long does it take to get from the Seattle airport (SEATAC) to the greyhound station by the convention cent? -

You can also take the link light rail - shuttle bus from the airport to Tukwila station, train from Tukwila to Westlake Center. Total time is about 45 minutes, and from there you ll need to walk to the greyhound station about 6 blocks away.From 19 December the airport station is supposed to be in operation, cutting the travel time to about 35 minutes.

i heard somewhere that greyhound is going be bankrupt so tehy would be out of businessand no service will be operatingwhere are you trying to go Vancover BC? (there is direct service on quick shuttle from sea-tac to Vancouver BC

You can get there in about an hour by taking the MT (Metro Transit) bus #194 from the airport and walking about 3-6 blocks.
