Hi, I'm traveling with Iberia for the first time. BER-MAD-BOG and return on Premium Economy.
How is seat selection on my case? On this forum I got the advice that I can get a good seat if I check in as soon as possible with seat selection.
On the website it says that I can select seat before 24 hours and after 24 hours I get a randomly allocated seat. So at which point can I select my seats for free?

Right now, I tried checking in, but it was trying to force the paid seat selection, so I didn't continue the process. The flight is in 2 days from now.
