Just returned from a PE trip to central Afrika on the B777-200. What a terrible seat. If you have any kind of back or neck issues do yourself a favour and book business (or even economy).
Flight was about 6hrs, stay-on-board stop, and another short 1 hour flight. In total probably 9 hours for the outbound flight, 6 hours for the direct return flight. Only the main meal was served, no second meal prior to arrival. On the return they did come round with coffee, tea or water...almost 90 minutes prior to arrival. Terrible for sleeping considering its a night flight of 6 hours length.
Duck pie ex-CDG, not terrible. Not great either. And why do they serve champagne in these plastic cups when there is a glass on the tray..
Return to CDG they initially served us an economy meal. After inquiring about why we did not receive a PE meal (Sitting in PE) the meals were exchanged. The mains was much worse compared to the outbound, the chicken and sauce was pretty tasteless. Bread literally a mix between a rock and chewing gum - cold, tough and chewy. Vegetable appetiser was okay.
The chocolate cake is good, I believe it's similar or the same to the one served in European C class.
