Four airlines cover this Orlando to Tromso business class routing well. British Airways runs its Club Suite through Heathrow — a proper suite with a closing door, 1-2-1 configuration so every passenger has aisle access, and White Company bedding that's a notch above typical amenity kits. Virgin Atlantic's Upper Class, also via Heathrow, gives you the same door-equipped suite plus access to the Clubhouse lounge and its social bar, which is worth arriving early for if you have a long layover. Delta's Delta One Suite connects through Atlanta or Minneapolis, with a similar privacy door and Tumi kits, and tends to run some of the more competitive fares in this range given Delta's Orlando presence. United's Polaris, routed through Houston or Chicago, uses a lie-flat pod rather than a fully enclosed suite but includes Polaris lounge access and Saks Fifth Avenue bedding — a solid option if the connection timing works better for you.
