I’ve been eyeing the prices for roomettes on the Empire Builder from Glacier National Park to Chicago and last week the price for two adults and two children was under $1300 (for 2 roomettes), 11 months out. Just a couple of days ago I checked and the price increased to $2300, also 11 months out. I can’t even buy my tickets yet because we’re planning this for mid summer of next year. I’ve been reading all about the need to book as soon as possible, and discussions about buckets. Any insights on why the sudden increase? (In two days, I should finally be able to buy tickets based on the dates of travel.) Thanks!
