Hi Olly,
I've just booked the "Parks & Canyons" holiday from Heathrow on June 6th.
The brochure says the flight from Heathrow to Phoenix will be with United Airlines departing at 13.05.
Checking on both the Heathrow and UA websites I can find no record that this flight actually exists.
I'm a little concerned because I've booked a airport hotel (& parking) the night before as I'm travelling dwn from Yorkshire and didn't fancy doing it on the morning.
Can you confirm flights/airline is correct ?
Thanks
Mick
