Nobody in their right mind wants to sit in the last row of any airplane where one is constantly listening to the toilets flush or the clanging and chit chatter of the flight attendants in the galley not to belabor the point that the seats do not recline. So how do you get the best seat available?
Check out the following websites: SeatExpert.com and SeatGuru.com.
Both provide seat configurations of most planes, but the advantage Seat Expert has over Seat Guru is that you can sign up for seat alerts to change your seat should a better one become available.
(Sorry I couldn't provide the links to these sites as I am in the a part of the country that doesn't allow me access to include hyperlinks in my blog. Technology is great until it's not.)
