In June 2019 we flew from Seoul Incheon, to London Heathrow, and I made a video about my experience. For my return journey on the same 787 Dreamliner I didn't plan to make a video of the return journey but I found a few differences so wanted to share this experince with you too. The main ones were that you got a glass of prosecco upon boarding the plane, the blanket, pillow and amenities kit had changed and there was no snack pack at the back of the plane, they handed out Magnum ice creams half way through the flight instead. However you were able to eat left over pretzels if you were still hungry. You can see my previous video here but please comment below if you have any further questions. 787 Dreamliner. https://www.youtube.com/watch?v=Ve7l5wOTZuI&t=15s
