Expedia has Best Price Guarantee that promises to match lower price (certain exclusions) and give you $50 hotel coupon for the hassle.
There are some caveats that you must take into account i.e. the comparison website must be in English, charge in USD, and based in the United States.
You can access Expedia’s Best Price Guarantee here.
Here’s update on the minimum refund that is now in place:
Thank you for contacting Expedia about your Best Price Guarantee claim associated to itinerary (removed).
We apologize for the delay in answering your BPG request. We are currently experiencing an extremely high volume of price match requests, preventing us from responding within our normal standards.
We have great news!
We have reviewed your claim and it has been accepted. We are unable to process refund for values less than $1.00. Rest assured, we added a $50 Best Price Guarantee coupon in your Expedia account and it is now available for redemption.
For future correspondence, please send your e-mails to our dedicated Elite Plus Support Desk at “firstname.lastname@example.org” or give us a call at 1-800-397-1207 or 1-702-939-2635 for callers outside U.S. and Canada.
What I have gathered from some recent Best Price Guarantee attempts is that they do have a look at the claim almost immediately, but only reply weeks (in this instance 6 weeks) after the successful claim is filed. For those that they deny, you tend to receive the reply within few hours/max a day.
I tend to purchase quite a bit of flights on Expedia and it is not uncommon to find the same flight(s) for few cents less on Priceline or Orbitz (the latter will likely change if they bring it on Expedia’s platform) and I just keep filing these claims.
The $50 Best Price Guarantee coupons come handy when you need a quick overnight and non-chain hotel is an acceptable choice.
I have not find, whoever, any benefit for being an Expedia+ Gold member beyond earning some extra points.
