Seatguru has been awful for years (since they were bought by Trip Advisor). Seatguru lacks both many new aircraft and also lacks updated aircraft configurations. For example, Seatguru's seat map for the Delta A330 doesn't have the layout with PS. For Delta, Seatguru doesn't have the ex-LATAM A350 configuration. Seatguru doesn't have the A220-300 (it does have a seat map for the A220-100). Seatguru also still has seatmaps for types that have been long gone such as the 777 and MD-88/MD-90. And Seatguru just now puts in boilerplate assessments for certain seats that are often not accurate.

A better website to utilize is Aerolopa (https://www.aerolopa.com/) which has more detailed seat maps and more accurately depicts which seats have legroom, are missing windows/misaligned windows, proximity to lavatories, etc.
