The code changes a line on the summary. What changes the outcome is the rate you picked and who owes you money when the trip moves. A refundable and a non-refundable version of the same room can sit a few dollars apart at booking and hundreds apart the day plans change, and that gap dwarfs almost any discount on this page. There is a second thing the tariff hides: you are buying through an agency, not from the airline or the hotel, so when something goes wrong there is an extra party in the chain. Settle the cancellation terms first, then paste the string.
Most of what moves a travel total is not entered as a code. It is chosen at the rate, at the payment step, or in the account you booked from.

The air ticket is the one part of this booking with a legal floor under it. US Department of Transportation rules define a significant change and force a refund whenever you decline the alternative offered: a departure or arrival shifted by more than three hours on a domestic flight or six on an international one, a different departure or arrival airport, an added connection, or a downgrade to a lower class of service. Once a refund is due it must be paid within seven business days on a credit card and twenty calendar days on every other payment method. Checked-bag fees come back too when a domestic bag is not delivered within twelve hours of the flight reaching the gate and you have filed a mishandled baggage report.
What catches agency customers is who has to perform it. The automatic refund obligation sits on the carrier. A ticket agent — which is what this site is on that transaction — owes you a prompt refund when one is due, but in practice you have to ask, and the request travels through the agency rather than straight to the airline. Hotels have no equivalent floor whatsoever: there is no federal right to cancel a US booking, so the only deadline in existence is the one the individual property wrote into the rate.
Before deciding a code is dead, walk the offer card it came from. Product scope is the usual culprit, because travel offers are written for one thing at a time: a hotel offer does not reach a stand-alone flight, a car, a cruise or, often, a flight-and-hotel package. Channel catches a lot of people, since some offers are issued for the mobile app and never render on the desktop site. Rate type matters, because offers routinely name the rate they apply to and quietly exclude the rest. Sequence is final: nothing can be applied to a reservation that has already been paid for, and there is no retroactive path back. And when a code does go in but the figure barely moves, compare totals rather than line items — on a travel booking the taxes, recovery charges, resort fees and carrier charges are quoted separately from the rate and are not what the discount is measured against.
Travel discounting follows the booking window rather than the travel window, which is exactly why hunting for a code in the week you fly almost never works. January is the deepest booking month in the American market, when the industry sells the year ahead. The Tuesday after Cyber Monday has become travel's own sale day and is the densest cluster of travel promotions in the calendar. Presidents Day and Memorial Day weekends anchor the spring, Labor Day closes the summer, and the genuinely cheap domestic weeks are the shoulders on either side of it — early September and the first half of December. Summer is peak, and offers thin out precisely when demand is highest.

When not to book here: when you need a flight and nothing else. An agency in the middle adds a party to every refund you are owed, and the obligation to refund without being asked rests on the airline rather than on the agent, so the cleanest version of that purchase is direct with the carrier. Price the two membership routes on the Costco and Walmart pages before committing, or scan every US retailer we track from all stores.
Sign in first, then take the reservation through to the payment page. Open the box labelled for a coupon or promotion code, paste the string in and confirm the figure on screen has actually changed before you finish. If nothing shifts, it has not attached.
Assume not. Travel coupons are normally issued one to a purchase and written so they cannot be combined with other offers. If you are holding two, apply each in turn and keep whichever leaves the lower total.
Every code here is tested in the Expedia checkout before it goes live and re-tested in our daily review. Ones that stop working are marked expired rather than deleted, so you can see what has recently been available instead of an empty page.
Try the next one on the list, since several usually run in parallel for different products. If none apply, sign in and re-price the same dates while signed in — member pricing on selected hotels needs no code at all and often lands lower than the expired one would have.
That depends entirely on the rate you booked, not on the site. A refundable rate cancels free up to the property's stated deadline; a non-refundable one usually returns nothing. Open the reservation and read the deadline before you call anyone.
