I have a trip planned for next month and I'm not sure what documents I need to bring. Is a passport enough or do I need a visa? I'm also wondering if I have to print out flight confirmations or if having them on my phone is sufficient.
Your passport is obviously mandatory, but what most people forget is to check the expiration date - some countries require it to be valid for at least six months after you return, so verify it now. Flight confirmations on your phone are fine, though some older airports still ask for paper (better to have screenshots just in case), but the critical thing is the visa: some territories require it at entry and won't let you through, others you sort out online before you arrive, and some don't need it at all - it all depends on your nationality and destination, so spend five minutes on the immigration website of wherever you're going.
It depends on which country you're going to, but you definitely need your passport, and then check if they require a visa (some countries do, others don't). You can keep your flight confirmations digital on your phone and they work perfectly fine at the counter, though if you want to be extra safe you can also print them as a backup.
Don't just rely on your passport without checking the specific requirements for the country first: some require a visa, others need documented vaccinations or travel insurance. Flight confirmations work great on your phone, but what I'd do is take screenshots of everything (flights, hotel, insurance) and save them to the cloud or email too, just in case your phone dies or you lose it on the way. Also make sure your passport has enough validity (many countries require a minimum of 6 months from your departure date), and keep a photocopy of your passport number separate - better safe than sorry.
