If possible book business class. If you have "miles" with an airline there are many ways to upgrade for cheap or free. Calling the airlines rather then booking on the web will also increase your change of a good fare. Fly nonstop, please fly non stop. Depending on where you travel from it makes big difference in trip length and unessesary running arround at a stop over airport. Depending on your problem buy multiple coach seats early when the prices are low. I was planing on 4 (!) seats, the WHOLE centersection of the plane but luckily I was able to book business class using my airlines mileage program. I needed it, both ways.

Good luck!
