I figured out that there is a spelling error on my airline ticket, just an extra letter 'A' in my surname. I called the travel agent and he said there will be no problem. I am travelling from USA to Nepal in five days via Abu Dhabi . Do any of you guys have suggestions or experience to share  regarding this issue? 

I will update this thread after I return (hopefully without any hassle!) with my experience.

 You might face a problem @domestic airport of here and while coming back. So better tell them to change it back to your original name. Hab fun in Nepal.

 I had same kind of spelling error problem on my plane ticket  when I came to USA first time. I was also worried about that but I didnt face any problem in any airport.so, I don't think it will create any problem
