Overall happy, website experience could be much improved, but I'm sure they have their reasons for the current layout (optimizing for something)
I don't like that many times hotels are treating expedia orders like second rate, and the process of changing dates, etc... can sometimes be tiresome, as well as vague value of points, but so far helped organize trips with multiple stops, etc... and doesn't look like any of the alternatives are much better.
They already have collected data from others who snooped on you.
If you enable any social media integration they get the right to harvest the data on your friends- with that much data they know EVERYTHING!
It appears they pass on slightly less data than some competitors- but they don't restrict what 3rd parties do with it. That one is BIG!
They do use LSO supercookies.
Some of their opt-outs are a bit better than many competitors.
Using it through a phone may be unwise and you probably want to shut geolocation off.
I have used Expedia twice in recent months for flights to both Orlando and San Francisco. I am confident that the prices I found my flights for were the lowest available to me via the Internet.
Additionally, I had to change my flight home (from Florida) through United Airlines directly and was worried about receiving flak using a third party. However, it was handled accordingly.
I have not gone to this website in well over a year. I have never made a purchase through them or even given them my email address, yet they just started spamming me on a very regular basis a couple of weeks ago. I have no idea how they got my email address and they will not respond to my requests.
I use this site all the time, they have a good price range for hotels and flights. The customer service is awful. If something wrong with your booking, be prepared for the long painful waiting on the phone.
