I don't know why the charges are so high. Last time I went to Chicago with OneTravel because I heard they are offering good packages. The service was not so good as I expected. The seats were not much comfortable. Food was not properly cooked due to which I had loose motions. I think they should lower their prices for such a service. Does anyone know any good site for booking tickets at the best rates? But the overall services must be better than my past experiences. Any good suggestions?
