On some pages, you can select how to sort the results we display and also use filter options to see only those search results that meet your chosen preferences. You'll see explanations of what those sort options mean when you select them.
If you see a Badge of Excellence label, the award is based on average review ratings, share of bookings with a review, and number of bookings through City Helicopter Tours over a 12-month period.
The importance of any one factor over any other in a sort order varies, and the balance is constantly being reviewed and adjusted. We're always updating our systems and testing new ways to refine and improve your results to make them as relevant as possible to meet your needs.

City Helicopter Tours uses three different cancellation policies, depending on your specific Tour or Activity. Please be sure to verify which one applies to your chosen experience before confirming your Booking.
This information can be found on every Experience we offer under the Cancellation Policy section, as well as on the checkout page.
Standard Cancellation Policy — A majority of our activity cancellations are free up to 24 hours before the activity commencement time (based on the local time of the activity).
All Sales Final — If any Goods or Services are designated as ‘All Sales Final’ or with materially similar messaging (which includes but is not limited to all group bookings booked through our Group Bookings Department), it is non-refundable, and it will not be possible to change or cancel it after making a Booking for any reason.
Non-Standard Cancellation Policy — A minority of Goods or Services have other, different cancellation policies. In all circumstances, you must check the cancellation policy contained in the applicable Product listing at the time of your Booking, which is the policy that will apply to and govern the terms of your cancellation and any refunds.
To cancel your Reservation you must contact City Helicopter Tours as soon as possible.
Cancellation Due To Bad Weather
If your Activity Operator must cancel due to bad weather and cannot accommodate you on another day, you will be issued a refund. Please be aware before issuing a refund, City Helicopter Tours will confirm if this is the case. Please note, this is only a valid reason if the Tour Operator cancels the tour.
If Tour Operator Cancels Tour or Excursion
If, for some reason, a Tour Operator cancels and cannot accommodate you on another day or at another time, you will be offered a refund and the option to take the trip. In the event of cancellation due to bad weather, City Helicopter Tours will confirm this before authorizing a refund.
Showing Up Late
If you or a member of your party shows up late and are consequently not able to participate you will still be responsible for the full amount of the Tour, Activity, or Excursion.
No Shows
If you, or a member of your party, do not show up for your Tour, Activity, or Excursion you will be responsible for the full amount of reservation.
Unsatisfactory Activity Experience
If you experience an issue of any sort with a Tour, Activity, or Excursion you have booked via City Helicopter Tours, immediately bring this to the attention of the Tour, Activity, or Excursion’s operator. Make your concerns and complaints heard with the person in charge so that you may reach an agreeable solution immediately. Do not wait until you return from your vacation.

To the maximum extent permitted by applicable law, in no event shall the Company or its suppliers be liable for any special, incidental, indirect, or consequential damages whatsoever (including, but not limited to, damages for loss of profits, loss of data or other information, for business interruption, for personal injury, loss of privacy arising out of or in any way related to the use of or inability to use the Service, third-party software and/or third-party hardware used with the Service, or otherwise in connection with any provision of this Terms), even if the Company or any supplier has been advised of the possibility of such damages and even if the remedy fails of its essential purpose.
