What should a traveler expect from the experience of flying business class on this route? The 3.6-hour average flight time from SEA to STT is short enough that the value of a premium seat is less about lie-flat beds and more about priority boarding, enhanced service, and arriving in the U.S. Virgin Islands without the fatigue of a cramped economy cabin. For executives and frequent travelers, that quality-of-arrival calculation matters — especially when the fare gap between cabins narrows through private pricing.
