Before I get into the actual report, I should note that I checked the seatmap just a couple of hours before the flight, and it showed just two seats taken in business class (including mine). However, economy was oversold, so there were 22 upgrades from economy to business class.
I boarded through door L2, located right behind the business class cabin. There was a very cool-looking display with the Royal Jordanian crown logo on it, though I don’t think they ever did anything with it during the flight.
While most airlines have proper bulkheads between the main entry door and the cabins, that’s not the case on Royal Jordanian’s 787. Instead the second set of doors opens up immediately to the back of the business class cabin.
