I used this app to book my entire European trip for the summer including planes, busses, and trains. The app is helpful in finding different transportation options and mapping out how to get from point A to point B. However, Omio is famous for increasing cost of trips compared to what the ticket costs actually are at the original vendor’s price. The app also does not show you all of the available departure times and different transportation options that are available. It also is not helpful in providing updates such as seat assignment changes and departure/ arrival changes - which I can see creating issues for people who book and plan trips months in advance but don't recieve updated tickets. Hopefully this is a bug they can fix in the future but as for now I look for updated tickets on the vendor websites because my Omio app always had outdated seat assignments/ departure times. The Customer Service team is helpful and easy to get in touch to talk to someone without long waits. In my experience, booking my trip a few months out on the Omio app showed only 4 trains leaving some cities each day, when the actual vendors showed options leaving hourly. I am not sure why Omio doesn’t have their apps updated and synced with vendors but hopefully that changes soon. Ultimately, its a great app to find out what transportation options are available to different locations but with the uncharge on prices and the lack of updated transportation options and not updating the ticket information on the app, I would say there are cheaper and smarter ways to travel without this app. Omio made my European experience more difficult than it needed to be but hopefully if they fix these issues, it can be a better app with a lot of potential in the future.

Used this company to book two train trips. 3 days before my first trip, Omio sent me an email informing of a strike that would effect my travel. Being on vacation, I quickly booked flights to avoid dealing with any hassle of trip interruptions. A day before the strike was supposed to start, I had learned the strike had been called off. Omio informed me I needed to contact the train company to receive a refund. They blocked my credit card company from reissuing me my money. Omio customer service through email told me multiple times that the process for a refund can be done online, however, after asking multiple times for screen shots on how to do it, another agent told me it was not possible to do online and everything had to be physically mailed in. I had mailed my information in June to the train company and still have not received any word on if I will be getting a refund. Because of Omio’s email, they should have refunded me my money. The second trip I had booked through them went without a hitch. I would caution using Omio and book directly with the train company as much as possible.

So it is easy to find and make train reservations, but when it comes to making changes… WOW! Omio is not user friendly. I had issues with my trip so I had to make changes for the trains and trying to figure out how to reach customer service was awful. They don’t have a chat services and then when I finally found how to email them it would give me an error that I couldn’t make changes to that confirmation which was frustrating but I could send the email anyway. Then, customer service doesn’t really until hours later. Just hope you don’t have to make changes on your trips because then it’s a mission and can’t get things done. I had to pay for all new tickets all over again. Just be careful if you decide to use Omio - if your for sure that your plans don’t change then go ahead but you can never plan for mishaps on the trip and changes but they don’t care.

I booked the train tickets on the app between Bolzano and Venice 2 days before departure. It was my first time there, so I was unaware of scheduled strikes in Italy. When I showed up at the train station all the trains were cancelled how it was scheduled long before!

Omio failed to mention this crucial detail during purchase, didn’t send any emails about cancellation, which would have saved me money on a taxi, and should have never sold those tickets in the first place. 

They refuse to help in any way with refund, saying I have to deal with it myself with Trenitalia, which proved to be extremely difficult, when you don’t live in Italy, and extra difficult because I booked it through Omio! If I’d have gotten tickets from Trenitalia, they’d be able to refund immediately at the station. 
And this was not the only instance they refused to help.

It ruined my trip and I am still waiting for a refund 4 months later.

The tickets were also more expensive than if I just got them directly from Trenitalia, so don’t be a naive tourist like me. It might be convenient at first, but you’ll end up paying more and if you have any issues they won’t help you.
