Coupon codes have long been used by travel purveyors such as car rental companies, hotels, motels and airlines. They may result in a lower price, just like traditional coupons. Other coupon codes will be good for a free upgrade, for example, from a mid sized car to a luxury or SUV type model. With the hotel and motel offers, a coupon or coupon code will entitle the customer to a free room upgrade or, in some cases, an extra night free. You must be certain to enter these codes at the time of booking, as most travel purveyors will not honor them at time of payment. It is generally the policy to hold a certain number of rooms solely for promotional customers and with car rental, fulfilling the coupon offer is always based upon availability, which changes, not only with the date of rental but also with the location of desired car rental.

Airline coupons and coupon codes are usually preferentially given to members of the specific airline's frequent flyer club. They are a customer loyalty technique that rewards and draws repeat customers. These offers must be redeemed at time of booking and will usually be good for a lowered price. However, many airlines offer specialty coupon offers to business travelers. These are in the form of free upgrades. The airline is hoping that exposure to this more comfortable form of travel will become additive to the businessperson who routinely travels often and makes several business trips monthly.
