Travel Arrangements

<p>Hello,
I am from Nepal and I am going to the US for further studies. the cheapest travel arrangement I have found is from Thai airways which flies from here to BNK and then to JFK in NY. I need to get to Colombus but I have found out that there is no flight from JFK to Colombus on the day I am supposed to get to NY. I really dont know what to do next. Should I look for another arrangement (which is definitely going to be expensive)? What I want to know most is, will I be allowed to possibly to go to another airport in NY and board a flight to Colombus? And is it feasible with the bags and all?
For the record, a friend is going to be with me as well and it is our first time in the US.
And can anyone inform us what the fare from NY to Colombus is?
I look forward to ur help.
Thank you.</p>
