I have been flying with Qatar for about 5 years now. To me, Qatar is the best airline in the world, hands down. Yes, there are other great airlines, Emerits, Etihad, ANA, etc but Qatar covers all the bases.
If only Qatar airways flies from LA to Miami then I would fly them every single time I travel to Miami. Qatar airways is one of if not the best international airline I’ve ever flown on.
The worst airline in the world where they do not allow you to modify travel details, and the only solution is to cancel the ticket and deduct more than half of the amount. Based on their employees' instructions, I changed the ticket to a voucher, but the voucher had the same previous information and cannot be used. Unfortunately, it has expired and I lost nearly a thousand dollars. I hope everyone sees you for who you really are.
