Sure! Since I sllways go to the airport using trains

I have 1 tatonka barrel that doubles as a backpack

The four rollers that I combine on the handles with a 1€ strap from wish and my carry on is strapped to the last big bag its quite comical when even Japanese tourists point at me

To be fair I only have 5 bags COMING back from the states going over I usually have 2 as I pack the other bags inside

Use the whee chair door to enter the train and if you are going to the main station then pick The first unit so you will be closest to the station!

Of course this advise works best for insane people who bring tons of American food that is super expensive here

A cab works well if only going to Helsinki, but I live in the boonies 😎
