1st - those who fly RJ to the far east are those who look for the cheapest flights available. Same like those who flew (and probably will fly soon) FF(Tower Air). Biz class is not an option for them.
2nd - Runways at airports have names in numbers which mark their direction in degrees. When a pilot lands on the wrong runway it means that he doesn't know his way , or doesn't look at the meters in the cokpit!
3rd - RJ is one of the only airlines that demand reconfirmation of flights(Even El Al doesn't any more!). A friend of mine went into this problem - try to reconfirm your flight from a mountain somewhere in Nepal!
When he got back to kathmandu he got on the flight to amman after many shouts at many officials there , but he didn't have the same luck in amman to TLV.

Buttom line - if you are looking for the cheapest, you will probably fly the cheapest you can find without considering the level of service. If you look for service and comfort , don't fly the cheapest.
