Need you comments on attached program.

[jude]

I am a novice in C++ and I am really interested to learn it more.I tried to write a program on flight timetable(for fun) which help travellers to plan their flight according to their preferences such as shortest flight, cheapest flight as well as be able to check for delay and cancel flights.Here are my program code so far.I would appreciate if you can comments on my program, so that it be more flexible or be declared in proper way.Thanks for your comments.This program is not completely finish yet as I am having some difficulties in how to declare/distinguish cheapest flight(first class,economy class etc) and shortest flight(direct/transit flight).Please advice.
