When I booked this flight months ago I had heard that United Airlines was planning on retiring its Boeing 747 fleet. I was glad to have the opportunity to have been able to book one of the last flights between London and San Francisco. I believe these flights end on the 28th of October and the last commercial use of the 747 will be between San Francisco and Hawaii in early November (sold out). Even though my ticket did not allow for the complementary upgrade to business or first class I was able to at least get into economy plus. We also lucked out that the flight was not full and both my wife and I, along with several others, were able to have entire rows of seats for ourselves. While not as comfortable as the lay flat beds in business or first class, just to be able to lay down on the 11 hour flight was a blessing. This made us so thankful that this was not a full flight as both of us may have gone stir crazy. As a long time United Airlines flier I did thank that the service by the flight crew could have been better, especially given the fact that this flight was lucky to be even 50% full. At times I felt that I was being ignored during the standard drink and food service order, even though I was awake and sitting in my seat. This was the first time that the flight crew actually stated that you needed to have your try table down for them to serve you even a drink. My wife and I both thought that the overhead entertainment choices could have been better. A cartoon movie, a movie that was released 2 years ago and finally a 13 year old movie were shown. While you could take advantage of the personal choice selections on your phone or tablet, I seem never to be able to get that service to work despite making sure that the latest app version has been installed on my equipment. Sorry if my equipment is only 2 years old, it should work. The balance of our flight went well and we both departed and landed on-time. Getting through customs at SFO went smoothly. Even with these minor glitches, I will remain loyal to United Airlines and hope that they will improve upon their in flight entertainment options, in part because not everyone can fall asleep on a plane and there is only so much reading material that you can bring on a plane (no I do not like reading books on a tablet).
