Booked online 2 days before we went, booking and communication 1st class, hotel pick up on time and a short ride out to the heliport.
We shared the excursion with a German family, really great that they make sure everyone gets a turn at sitting upfront.
The flight was amazing with a very competent (and funny) pilot, the views are to die for and landing inside the canyon itself for a glass of champagne and snack was awesome, yes it's quite expensive but you only live once, highly reccomend this company
