Additional tax charge on already booked flight. No e mail received. BookingHC3YDB?

Answer 1

Which airline? When you book a ticket online, you get a confirmation code similar to the one you gave us. Where did you book your travel, and which airline(s) are you flying on? I don't need passwords or credit card info or any of that; I just need the airline(s)'s name(s), and the website(s) where you booked your travel.
Tell me this, and then I'll tell you what you need to know.
