How can the airline deploy the oldest 757-200 with a broken down entertainment system and no WiFi for a cross Atlantic 7:50 hr torture chamber experience?? My seat 3A couldn’t be reclined. The footrest was flimsy and useless. And there’s no leg support unlike their newer 737-Max which they lavish on intra-Europe routes. Shame!!
