Flew with united but was disappointed that there was no individual monitors for inflight entertainment surely they are a must in the 21st century. What made this disappointing was I’d done my research and looked at their planes all showed monitors in the back of the seats. It was only at checkin at Dublin was I told that the aircraft had no screens and films etc were only viewable via their app. More annoying I had only an iphone8 with no headphones so I had to buy an adapter. Luckily I had the app downloaded but the amount of passengers who didn’t wAs I’d say the majority. And try downloading anything using airport WiFi near impossible if you hadn’t before arriving. Also I left an iPad at home as I didn’t need it. If their website had made all of the above clear there would have been no issue but it didn’t. Also a stewardess told me there was no charging on board for devices. Strange as I found one half way during flight which is not usb but an electrical (American) plug connection I mean no usb charger in 2018?? Either the Irish passengers are being treated as 2nd class or united haven’t moved with technology I believe the former. I won’t be travelling with them again because of the above. Why should I? When AA Aer Lingus delta provide In flight entertainment with individual screens.
