Comments and Reviews from users:

Dave Kaminsky: “Upon updating the app, it appears that a lot of the previously removed functionality has been returned to the app. Estimated prices in the date window are back, although somewhat less expansive that I would hope (and fewer than appear using google flights). The bar graph view is not here though, which is disappointing. The explore feature doesn't feel streamlined and feels a little too "curated" for my liking. Estimated prices for suggested travel cities don't show up in the explore page.” – 3/5 in Play Store

Comments and Reviews from users:

Andrea Enright: “The app since they changed to OneKey points will not let me sign in. I've tried so many times and it always tells me it's something on their end and to try again. Well I do try again, and same thing with the same result. Edit 03/24: the above was fixed on their app but the app is still not functioning 100%. I just booked a car rental that I cannot change or cancel. The app at some point switched my drop off time while I was searching and booking the rental. Frustrating!!! Please fix your app :(” – 2/5 in Play Store

Terry Rosenbaum: “The Expedia website has more features than the app. For example, while you're changing filters the website updated the count of matching properties. The app doesn't do that. The website map seems to be more responsive than the one in the app. I hoped that the app would be better than the website but it's not. Uninstalled the app and went back to the website.” – 3/5 in Play Store

Cons Hopper has been criticized for its fees and lack of customer service.

Comments and Reviews from users:

Hugh Hartigan: “I've used Hopper for a very long time and generally love it. However, recently, I am unable to watch flights. If I attempt to add one, it shows it as "Watching", but then never shows up on my tracked flights list. I've attempted to reach out to support, but it's been difficult to get help. This is the main reason I use Hopper, so any help from their team would be very much appreciated!” – 2/5 in Play Store

Alex Forrester (PhatKidDMG): “I really like hopper, I moved from my home town to Denver about 4 years ago and they have been my default travel planner. For a 30ish year old person the integration and notification speed is helpful and I don't feel bothered by the app. It's come to my attention at other times I could have saved a small % more money using a competing service but often I feel the hopper cash and booking benefits outweigh those times. As well as connecting with Delta to get my skymiles. Keep up the trees!” – 5/5 in Play Store

Comments and Reviews from users:

A Google user: “Ads used to be the same size as the other listings. Now they're huge, take up 2 screens worth of scrolling, and pop up while scrolling or attempting to click on a listing. This type of advertising doesn't work, no one wants it, and its driving people away from the app. EDIT: Thank you very much for fixing the ad issue. I had quit using it for a while, but after last update, the ads have went back to a reasonable size, and no longer take over the screen while scrolling” – 4/5 in Play Store

A Google user: “It used to be really good, but recently it's just awful. They often direct you to book at shady sites, half the time the price they show isn't actually available when you try to book (just repeatedly keeps saying "Booking failed" and suggesting trying again, without ever actually updating the prices), it's incredibly slow, and arguably worst of all, doesn't show the best deals, even when Skyscanner or the airlines' own sites do.” – 2/5 in Play Store

Comments and Reviews from users:

Dawn Zamora: “Easy to understand. Lists all the information I'm looking for unlike TripAdvisor. Gives me great prices as well. Thanks priceline! The only thing I don't care for is I can't see the hotel until I book it. Unfortunately the only hotel I have a problem with out of the 3 probabilities, I was booked at but can't change it. During my stay there was a double shooting, several incidents where the authorities were involved. And the rooms are missing a great deal of things such as towels, etc.” – 3/5 in Play Store

1 s s: “The app works well, but the discounts suck. Also, they only give discounts while you're already vacationing, and by the time you're off vacation the discounts are no longer valid. I have a gold membership, but the benefits aren't worth the prices you pay for hotels. Their service fees while booking are also very high, so by the time you get a little hotel discount the service fee brings the price right back to the original hotel charge.” – 2/5 in Play Store

Micah Medina: “I have gotten some really good deals with this app before. If you are a frugal person, I suggest having a good idea of when and where you want to go before searching. Airline prices are extremely volatile and you can find an excellent deal, but by the time you click on it, it's gone and the price might double in that minute or so that passed, which I find infuriating. Good app, I have been experiencing lots of errors though. I click on view deal and the page won't load or it will say error.” – 5/5 in Play Store

Firdousi Khatun: “cheap flights is very helpful when planning trips. Even if your original flight itinerary changes, they do everything they can to make sure you arrive to your destination in a timely whether it's for a vacation or business trip. Lynette A. from VIP support was very friendly and helpful when I needed to make. Easy to use, nice to look at, good customer service! I was worried other reviewers seemed like they had issues but they've been great with me!” – 5/5 in Play Store

Comments and Reviews from users:

A Google user: “This app compares flights and shows to us. But there are apps like farefirst which does it in a nicer way. Momondo does not provide cheap flight always, it is biased I feel. I wouldn't want to use this app again for booking. On the positive side, this app has a very very good user interface and user experience. The Colorado combination is eye catchy and has no words. Their website is also same. UI is great, but feature wise still below other apps.” – 2/5 in Play Store

A Google user: “updating this review. re-downloaded the app, the performance is spotty and unreliable at best. Not showing many flights, re-searching and pulling different results every time for same itinerary. App seems to freeze and fail frequently. Not sure what the problem is but competitor apps are fine. Good luck.” – 3/5 in Play Store

Comments and Reviews from users:

A Google user: “CON: I was booking a flight and in the middle of typing my card number the price of the ticket increased by $100. Same scenario, it increased again by $80 dollars. All within 3 minutes. The app will tell you they're not responsible for it. Either way once it increases, even if you've selected your ticket, the original price won't be honored. Not cool. PRO: After researching elsewhere I was still able to find the cheapest price for my trip.” – 3/5 in Play Store

A Google user: “App Used To Be Better. It had cool features like proximity search. The new interface is just okay. It's a little more confusing on how to set dates for travel, and a little easier to set one way vs return trips. It was always a little more expensive than Momondo but made up for that with an excellent fare calendar. My gut sense is the deals aren't as good as they used to be.” – 3/5 in Play Store

Comments and Reviews from users:

A Google user: “Don't use this app. This company doesn't honor the prices you see on hotels and car rentals. Every hotel and car rental I booked was followed up by a call from a rep stating that the price that the hotel I picked had changed and that I had to rebook the hotel again at a different price a much higher price. This is within 2 to 5 min after being charged. So not only have you paid once but in order for the correction to be processed (which will be WAY more) you would have to be willing to be charged again and wait for the first charge to be refunded to you and that could take anywhere from 7 to 14 days. DO NOT BELIEVE THE REP IF THEY SAY A REFUND WILL BE REWARDED WITHIN 24HR. This company also does not stand by the policies they post and will leave you left with nothing. Especially for car rentals.” – 2/5 in Play Store

A Google user: “I'm very impressed in how they handled a price change on a ticket during my booking. i instantly got a call, an agent carefully verified everything, didn't have access to my credit card info, and wasn't able to complete the transaction because the initial one did actually process. It would appear their data systems are properly set up and I was pleased with the thoroughness of the customer service.” – 5/5 in Play Store
