Aircraft and ages come from the planes each flight number actually flew in the last 3 months of data (FAA registry build years); airlines can swap planes. Legroom is the seat pitch the airline or a seat-map source publishes for that aircraft and cabin; we never estimate it, and seat maps change, so check the airline’s seat map when you book.
