I am booked on the Coast Starlight from Los Angeles to Tacoma in mid-June. I have put in a bid to upgrade to Business Class from my purchased Coach seat. If I do receive the upgrade, what perks go with Business Class travel, and how crowded would the car be? When I booked the travel, the train was around 5% full, but has since gone to 10%. In past years, this train was sold out in Coach with every seat filled. I'm looking for more room, fewer people and less noise than the packed-to-the-gills Coach car. Thanks for your help!
