I think it is fine to proceed the way you are preceding. The reason I do not see anything like [b]"Origin='SFO', Destination='Bom'"[b] in the requirement, at least the one that I a have received.
Regarding the GUI layout, I am stuck with the event handling.
In brief I have created an Input Panel and this will consists of all the combo boxes and Search button. Also I have table and table model. Latter I will have to place these two together. The problem here is how to write an event handling for these two. I know MVC approach will help me in getting good marks as well as opportunity to learn MVC. So I am rather working to come up with model (s), views, Controller. But so far not successful. I will read your post in detail latter and post my questions or queries latter.
