On this trip, I tried several modes of transportation within the EU

(1) Traveling entirely by FlixBus
(2) Airplane
(3) Railway

These modes of transport each have their pros and cons, and some aspects can be quite unbearable, but everyone can choose their preferred way to travel.

I chose to travel entirely by FlixBus because this type of bus service has night schedules, and the key point is that it’s very cheap.

For the airplane, to save costs, I took well-known low-cost airlines, including EasyJet, Ryanair, and Taiwan’s Tigerair.
In Europe, these low-cost airlines fly to specific airports, and for those cities you’ve never heard of, it’s important to check where exactly they are located.

I originally thought that passing through customs at small airports would be quicker, but how funny, I was completely wrong!!!
These low-cost airline dedicated airports do not have eGates to save costs, and customs checks are all manual. The internet connection is also very poor…

As for the railway, I used the German ticket from Deutsche Bahn (58 euros for unlimited travel within Germany), which is very cost-effective, but I highly do not recommend it. If you’re traveling within Germany, spending a bit more on IC or ICE trains will be much faster, although there is still a possibility of delays and long waits.
