I had to cancel my family's ANA flight booked via myTrip. MyTrip said ANA will charge around $160 per person for cancellation and the site will charge around $42 person. They also said taxes among some other things are non-refundable. Imagine my surprise when the amount they said they would refund was $132 out of $4,000+! They could not explain why. They just kept me hanging in their chatroom. I say never book here!
