You will need to carry your passport which is valid for at least 6 months after you return from your journey.
European Union nationals traveling within the European Union area (and to/from countries which have special travel requirements with the European Union) can travel using only a valid identification card. It is never a bad idea to have the passport handy as well.
The name on your tickets needs to appear EXACTLY the same as it is written in your official document. You can use just the initial instead of the middle name but it’s not always recommended.
If you recently got married and changed your name, be careful. If you already have a new passport, the tickets need to be issued with the new name. Name changes are not permitted by airlines once a ticket is issued.
Failure to match up your tickets exactly with the official documents may result in being denied boarding your flights until the ticket is reissued (which incurs change fees).
It is always best to check with the embassies of the countries you want to visit to make sure you know their latest visa requirements.
