CheapOair is an online travel agency that specializes in providing affordable travel solutions to individuals and businesses. As of my last knowledge update in September 2021, CheapOair offered a wide range of services related to travel, including:

1. Flight Bookings: CheapOair allows users to search for and book flights to destinations around the world. They provide options for one-way, round-trip, and multi-city flights, and they often offer competitive prices and deals on airfare.
2. Hotel Reservations: The platform offers a selection of hotels for users to book their accommodations. You can search for hotels by location, price range, and amenities, making it convenient for travelers to find lodging that suits their preferences and budgets.
3. Car Rentals: CheapOair allows users to rent cars at their travel destinations. This can be particularly useful for individuals or groups who need transportation during their trips.
4. Vacation Packages: The company offers vacation packages that bundle flights, hotels, and sometimes car rentals together. These packages are often designed to provide cost savings compared to booking each component separately.

• Sometimes merchants may change the commission paid and the Cash Back offer illustrated on our site may be incorrect. We take reasonable care and skill to ensure that the data provided on this site is accurate and up to date. However, we give no warranty of the accuracy of any information on the site and do not accept liability for any errors or omissions, neither do we accept liability for any resulting damage or loss. Further, we take reasonable care and skill to ensure the correct functionality of the website, however we give no warranty of the functionality and do not accept liability for any errors. By default, your applicable transactions will be credited in line with the commission reported to us by the retailer, which may be more or less than the advertised rate.

• We cannot be held responsible if the merchant fails to report your sale to us. Merchants have their own rules upon which they determine transactions to be genuine, i.e. An attempt to simply earn Cash Back by clicking/registering with no intention to continue to use/buy from their website could be deemed as non-genuine. These rules may or may not be advertised by us or the merchant and may be discretionary.
• Where a Cash Back enquiry has been successfully paid by a merchant, you may receive a lower amount than expected, this is due to the amounts received by us possibly being lower than the original claim. We do allow you to query this with us. If a merchant still hasn't paid a manual Cash Back claim after a period of six months, then we reserve the right to close the enquiry claim.
• 'Buyncashback' reserves the right to reclaim or make balance adjustments accordingly where it has been established that any credit has been applied in error. This will include but is not limited to transactions where the credit is not genuinely due or payout for any credited transaction has not been received from a merchant or its agencies. This can include transactions which are already marked as Payable in your Buyncashback account, or for transactions which have already been paid over to you by Direct Deposit or PayPal or any other means. Buyncashback reserves the right to apply fraudulent prevention measures as it sees fit.
