I booked a International flight for my wife which the itinerary had to be changed for some reasons. The initial flight ticket was with Air India Airlines which costed 820$ and when i called to change the reservation, they told me that there's a 250$ airline fee + the flight difference ( in their website it said 820$ for new dates, which apparently don't apply for change in reservation) + the justfly modification fee of 150$. So on a whole a change in reservation was 500$ when my initial flight was for 820$. And if you wanted to cancel the reservation, I would get back only 400$.
That was completely absurd. I mean who on earth charges a modification fee on top of airline fee. And when i wanted to speak to a supervisor about this, they put me on HOLD for more than 30 minutes and eventually i had to drop off the call and call them again.
I ended up paying 500$ for modification fee. I am not going to book with this site again and i strongly discourage anyone who wants to book through this site.
