How can i upgrade from economy to first class when my travel agent isnt ready to do so?
and hes giving stupid excuses which arent valid... my fathers medical condition is such that he needs first class seat in the airplane...can i sue this travel agent ? what are my consumer rights in this case?

Go direct to the airline involved. They may as k awkward questions about your fathers ailments though, be ready for that. Ont he other hand they may waive the extra cost for him, but I wouldn't rely on that.

sue the travel agent? you are kidding right?

since you don't list the TAs reasons who knows if they are "stupid" or not...

call the airline yourself and see if any first class seats are available for the flight, if there are, pay for the upgrade by credit card right there over the phone.
