The “best” seat in economy class on an airplane can vary depending on personal preferences and the specific aircraft configuration. However, here are a few factors to consider when selecting a seat:

1. Legroom: Seats with extra legroom, such as those in exit rows or bulkhead rows, can provide more space and comfort. These seats often come with additional charges or are reserved for passengers with specific qualifications.
2. Seat Location: Some passengers prefer aisle seats for easy access to the aisle, while others prefer window seats for the view and the ability to lean against the wall. Middle seats are generally less popular, as they offer less privacy and mobility.
3. Seat Position: Seats near the front of the cabin can offer a quicker exit upon arrival, especially if you have a tight connection or want to disembark the aircraft faster. However, keep in mind that seats closer to the galley or lavatories may be subject to more noise or traffic.
4. SeatGuru and Seat Maps: SeatGuru (seatguru.com) and other similar websites provide seat maps and reviews for various airlines and aircraft types. These resources can help you identify seats with potential advantages or disadvantages, such as limited recline or proximity to lavatories.
5. Recline and Exit Rows: Some seats, particularly in the last row of a section or in front of an exit row, may have limited or no recline. If having the ability to recline is important to you, consider choosing a different seat.

Ultimately, everyone has different preferences when it comes to airplane seating. It’s a good idea to research the specific aircraft and seat layout for your flight, read reviews, and consider your personal needs for comfort, convenience, and legroom when selecting a seat.
