Hi,
As I am sure you know, the seatguru maps used in EF are from SeatGuru, and have not been updated in years. The additional information about the seats is often no longer valid, or completely generic. Every bulkhead seat has the same legend about galley noise, etc. For example seats with wider footwells are not noted. Some layouts are not included in seatguru at all, like the Delta A350's they purchased from Latam and the United 789.

Any chance to source the information elsewhere?

thanks
