Do you want to know if you have a good seat before flying.  Remember not all seats are the same.  Some allow for more leg room or incline.  Some are close to bathrooms.  And who wants to get the dreaded middle seat.  So what can you do?  I have found a website that I use before EVERY FLIGHT.  It is called Seat Guru.  It is a free service.  Here is what a sample looks like

So lets say that you are flying on United Airlines.  One the Home Page on the Left Side there is a listing of Airlines.  So you would choose U-V-W.  Click on United. Then you will see

Now just enter your flight number and airline.  It will let you know what type of plane you are on.  It is important to realize that just because United flies for example from New York to Los Angeles each day they may not use the same plane type for each flight.   For those of us hoping for an upgrade you may want to select a flight with more Premium Economy or First Class seats.

Seat guru will show you the seat that you are in on a seat map.  it will also tell you if you have a Good Seat or a Bad One.
