This might be a bit of dumb question, but it’s my first time buying tickets to travel to Europe and I’ve heard that it’s better to travel with Ryanair (for example). I’ve read online about another airline but can’t remember the name now.
I’ve been checking their page, and it seems that there aren’t a flights everyday. To be more specific, I want to go from Madrid to Edinburgh and from there to Dublin, then back to Madrid.
Do you have any advice regarding low costs airlines? As in days available for flying, suitcase/carry-on, and stuff like that

Hi! I wanted to create an account on Substack and connect to Stripe for payments, but my country is not on the list of countries. What can I do to set this? Is it mandatory to use Stripe, or can I skip it?

I know I can mention movies, characters, authors, artists, song names without copyright issues, but in my story I want one of the characters to sing a verse of the song to the other as a joke. Would that cause any trouble in the future if my book gets published? Is a kinda popular song from the 80s. I don’t want to have any trouble in the future.
