How to get to Copenhagen?

In this post I want to present you some ways of getting to the capital city of Denmark.
1) you can fly from Poznan to Swedish Malmo and after in Malmo there's a bus going directly to Copenhagen.
The journey lasts maximum one hour and a half then it's very fast! The price of plane tickets starts from 39zl. It's so cheap! If it comes to the the bus' price, it's only 100 crowns ( around 62zl) for students.
2) you can also go on the bus ( for instance PolskiBus) to Berlin Schonefeld and in Berlin Schonefeld there's a flight to Copenhagen.
The journey from Poznan to Berlin lasts 3 hours and costs 40-50 zl and the flight to Copenhagen with EasyJet costs from 150zl to even more than 1000zl( particularly on the weekends) and it takes less than an hour.
3) you can choose a Flixbus going from Poznan straight to Copenhagen.
Unfortunately, this way of getting to Copenhagen is so long! It takes around 13 hours! The price is 100-200zl.
For me, the best option is the first one and I usually go like this :)
