Yes, seats are strictly assigned in advance on the Rocky Mountaineer for both the GoldLeaf and SilverLeaf service tiers. Unlike a standard commuter train, you cannot choose your own seat or move around to different coaches once the journey begins; the seat number you receive at check-in is yours for the entire duration of that specific rail segment. The Rocky Mountaineer team meticulously plans these assignments to ensure groups who booked together are seated together, although they cannot guarantee specific sides of the train. If you have a separate booking from your companions, you must contact the airline or your travel agent at least 30 to 60 days before departure to request to be seated nearby. While you are assigned to one seat, the bi-level GoldLeaf coaches feature a dedicated dining area on the lower level and an outdoor viewing platform, providing opportunities to stretch your legs. In SilverLeaf, all meals are served directly at your assigned seat. If your journey involves an overnight stay in Kamloops or another midpoint, your seat may change for the second leg of the trip, but your new assignment will be clearly indicated on your boarding pass for that day.
