Doprava ve městě Vídeň

After purchasing this card, you won't have to worry about queuing to buy tickets at all. The card is stored directly on your phone, making it convenient to use and preventing loss. Basically, you only need to show it when checking tickets; otherwise, you can pass through easily. Overall, it's very practical and highly recommended for purchase.

I used this service for a round trip. Vienna's trains don't have ticket gates, so after arriving at the airport, you can go straight to the platform. If a ticket inspector comes on board, simply show your smartphone voucher. The train is comfortable with luggage storage, and you'll arrive at Mitte Station in no time. While the CAT is a bit more expensive, it saves you the hassle of buying a ticket and gets you to the city center the fastest. If you're heading to the airport, some airlines allow you to check in and drop off your luggage at Mitte Station. I went early, dropped off my luggage, enjoyed a leisurely lunch, and then boarded the train. Although Mitte Station can be crowded, the CAT area is separated from the rest, making it a quiet and relaxing space. Staff members are always present and kindly showed me how to use the luggage drop-off machines. This is a highly recommended mode of transport for those staying in the Old Town.

The price is the same as the Eurail app, plus I can use Klook's own discounts and avoid the 1.5% foreign transaction fee, so of course, I'm buying it on Klook. The price difference between first and second class is only about 30%, and the experience will be much better. Plus, I can access the OBB lounge, which is where I've been having breakfast these past few days.
