I have flown on may different airlines in my days and I have to say that I absolutely LOVE Continental Airlines. My favorite plane they have would be the Boeing 767. This plane is used on longer distance flights mainly.
I have flown on the smaller planes of Continental Airlines and they are great too. The seats on all the planes are more comfortable then any other plane I ave been on. They are still not the most comfortable thing in the world, but the lumbar support is actually noticeable and helpful. The leg room is also very spacious with plenty of room to stretch.
My favorite part of riding in the 767 is the personal monitor every seat has. I had a long 6 hour flight but was never bored! I watched the free movies, popular TV stations, and played video games the whole flight! You even get personal headphones you can keep or give back if you do not want them after the flight.
The food was good too. Again, not gourmet food, but much more tastier than most airlines.
If I had the choice, I would fly Continental everywhere I went. They fly out of most major airports, but are not found in many local express airports.
