The site now has a "search by route" function allowing you to list and compare airlines flying from, say, London to Hong Kong, and compare the seat pitch offered by each of the airlines flying that route, either directly or indirectly.
Seatplans.com has hundreds of detailed editorial and user reviews, accurate seat statistics, pictures of many of the seats on board and of course unique seat maps to show you the layout of the aircraft you will be flying.
Each month seatplans.com will be giving away a prize for the best reviews posted by visitors to the site, and this month there's the chance to win a two-night stay at the five-star Le Mirador Kempinski Lake Geneva. There's no limit to the number of reviews you can post each month, so the more feedback you leave, the higher the chance you have of winning.
All reviews and the marks given also go to make up the Top Rated pages where you can see which airlines have the best economy, business or first class seats – as voted for by you.
