Using airplanes is necesary if you want to quickly travel far. But, not all airlines are the same, have same planes, seats. Also, airports have different standards. So, where to go, and which company to use?
http://www.airlinequality.com/ is a great page with many infos about airports and airlines. There are plenty reviews of airlines and airports, infos about best seats flying different airlines (watch the next time you book), seat pitch guides…
Actually, Adria Airways is a 3 star airline (out of 5) and the reviews are quite favourable.
http://www.seatguru.com/ is excellent site with description of seating arrangements in different planes and airlines.
For the ones who travel in style, http://www.flatseats.com/ is the place to go! It explains why old business sits in Lufthansa are not so good as the new ones.
And the last, but not least… general information about flying and companies, warnings, … http://www.uk-air.net/
