First time flying tips: everything I wish someone had told me before I got on a plane

The first time I flew internationally, I showed up at the airport three hours early, read the departures board for fifteen minutes before realizing I had no idea what I was looking at, and then spent a panicked seven minutes asking a stranger what “gate” meant and where the gates were.

The stranger was very kind. The gates were upstairs.

Nobody had told me any of this. There’s a general social assumption that airport logistics are self-explanatory, and they are, once you’ve done it twice. The first time, it’s a completely alien environment full of systems you’re expected to already understand. This is for people who haven’t flown before, or who haven’t flown much and want to feel less like they’re improvising.

Before you get to the airport

Check if you need to check in online. Most airlines let you check in online 24-48 hours before your flight, and some budget airlines (Ryanair, easyJet, WizzAir in Europe; AirAsia in Southeast Asia) will charge you extra if you check in at the airport desk instead of online. Do it in advance, save your boarding pass as a PDF or screenshot (you need this even if service goes out at the airport), and you’re done.

Know your baggage allowance. This varies enormously between airlines. Budget airlines often charge for checked baggage AND sometimes for carry-on bags above a specific size. Read your booking confirmation carefully and measure your bag if you’re unsure. The fees for oversized bags at the check-in desk can be spectacular.

The liquids rule. This applies in most countries: any liquid, gel, cream, or paste in your carry-on bag must be in a container of 100ml or less, and ALL of those containers must fit in ONE clear ziplock bag of approximately 20x20cm. Larger bottles will be confiscated at security regardless of how much is left in them. (I have watched people have a good cry at security over a $45 face moisturizer. Put the big stuff in your checked bag.)

Arrive early. For international flights, aim to arrive 2.5-3 hours before departure. For domestic flights, 1.5-2 hours. These aren’t just conservative estimates: if anything goes wrong (security queue, airline desk issue, bag recheck) you want time to solve it. Airports are also large. More walking than you’d think.

At the airport: check-in and bag drop

Find your airline’s check-in desks. These are usually organized by letter sections on the departures level (Level 1 in most airports). Look for your airline name on the signs or on the screens above the desk rows.

If you’ve already checked in online and have no bags to check, you can skip the desk entirely and go straight to security with your boarding pass on your phone.

If you have a bag to check, join the bag drop queue for your airline. They’ll weigh your bag, attach a tag with your destination and flight details, and put it on the conveyor. You’ll see it again at baggage claim when you land. Occasionally you won’t see it at baggage claim when you land (bags do get misdirected, rarely) and in that case you go to the baggage claim desk in arrivals and file a report. Airlines find most lost bags within 48 hours.

Passport. Keep it accessible for the entire airport process. You’ll show it at check-in, at security, at the gate before boarding, and at immigration when you land.

Security

This is the bit that stresses most new travelers. Here’s exactly what’s going to happen.

You’ll approach the security queue with your boarding pass and passport. Someone will check both. Then you’ll put your carry-on bag and personal items through an X-ray machine.

Before your bag goes through: take out your laptop or tablet (it goes in a separate tray). Take out your liquids bag (separate tray). Remove your jacket and put it in a tray. Remove your shoes if asked. In the US this is almost always required. In Europe and most of Asia, it depends on the scanner type and the officer.

You walk through a metal detector or a full-body scanner. If it beeps or flags you, someone will do a pat-down or wave a wand over you. This happens, it’s brief, and it’s not a sign of anything.

Collect your stuff at the other end. Put your shoes back on. Repack your liquids bag. Take a breath. Done.

The US has TSA PreCheck, which is a pre-screening program that lets you go through a dedicated faster security lane without removing shoes, laptops, or liquids. It’s worth getting if you fly regularly within the US ($85 for five years). International visitors don’t have access to PreCheck but Global Entry covers it and also fast-tracks customs.

UK and Europe: Similar process. The UK has its own security rules post-Brexit, so if you’re connecting through a UK airport, treat it as a separate security process with the same rules.

After security: gates, timing, and the wait

Find your gate on the departures board or on your boarding pass. Gates are usually in alphabetical/number sections and there will be signs. Give yourself time: airports like Heathrow, JFK, Dubai, and Singapore are ENORMOUS. Terminal changes sometimes require a bus or train.

Check the board for your flight number and the status. “Gate open” means boarding is starting or about to start. “Boarding” means go now. “Last call” means genuinely go now.

The waiting area near your gate: this is where most people sit until boarding starts. Some gates have cafes or food options nearby, some don’t. Buy food and water after security (water especially, because you can’t bring liquids through and the cabin is dry).

Boarding order. Most airlines board in groups. Business class and families with small children first, then economy in groups by seat section or by fare class. Your boarding pass will have a group number or letter. Wait for your group to be called before joining the queue, which genuinely reduces chaos and nobody boards faster by jumping in early.

On the plane

Your seat assignment. Find your row number (printed on the boarding pass), then your letter. Rows increase from front to back, letters go from window to aisle (A and F/G are usually windows depending on plane configuration). Ask a flight attendant if you can’t figure it out. They’re used to it.

Overhead bin. Your carry-on goes in the bin above your seat if there’s space. If your bin is full by the time you board (it happens on full flights when you’re in a later boarding group) they’ll stow it elsewhere on the plane and you get it when you land.

Take-off: the ear thing. As the plane climbs, cabin pressure changes and your ears may feel blocked or painful. This is very normal. Yawning, swallowing, chewing gum, or pinching your nose and gently blowing (the Valsalva maneuver) relieves it. Descending into landing does the same thing, sometimes more intensely.

Turbulence. The plane shaking. Also very normal. Modern aircraft are designed to handle turbulence that’s dramatically more severe than anything passengers experience on commercial routes. When the seatbelt sign comes on, put your seatbelt on. Otherwise, turbulence is uncomfortable but not structurally concerning. The flight attendants’ faces are the gauge: if they’re calmly doing their jobs, so can you.

Seat belts. Keep yours loosely fastened when seated even when the sign is off. Clear-air turbulence (the kind that appears with no warning) is the main cause of in-flight passenger injuries, and a loosely worn seatbelt costs you nothing.

Long flights. Get up and walk the aisle every couple of hours. Sitting still in a pressurized cabin for 8+ hours increases the risk of deep vein thrombosis (blood clots in the legs), especially if you have any risk factors. Compression socks help. So does staying hydrated. The alcohol-dehydration combination at altitude is also worth being aware of: alcohol hits differently on planes, and dehydration makes jet lag worse.

Landing and arrivals: immigration and baggage claim

When you land internationally, there are two things to get through before you leave the airport: immigration and customs.

Immigration (passport control): This is the formal entry checkpoint into the country. You present your passport and potentially a completed arrival card (many countries give these out on the plane or have digital forms you can fill out in advance). The officer will ask where you’re staying, how long you’re there, sometimes what you do for work. Answer truthfully and briefly. They stamp your passport and you’re through.

Long queues at immigration are common, especially at big airports (Bangkok Suvarnabhumi, London Heathrow, Tokyo Narita) during peak arrival times. Budget time for this. Some airports have e-gates for passport chip readers that are much faster. In the US, Global Entry members skip the line and go to a kiosk instead.

Baggage claim: After immigration, follow signs to baggage claim. Find the carousel number for your flight on the screens. Wait. The bags come out on a conveyor belt. Grab yours. If your bag hasn’t appeared within 20-30 minutes of the last bags coming out, go to the baggage claim service desk.

Customs: After baggage claim, you pass through a customs exit. Usually there’s a red channel (something to declare, usually items over the duty-free allowance or restricted goods like certain foods, plants, or large amounts of cash) and a green channel (nothing to declare). If you’re unsure whether you need to declare something, err toward the red channel.

Australia and New Zealand have strict biosecurity. They have separate biosecurity declarations on top of customs, and they take it seriously. Declare any food products, plant material, or soil on your boots. The fines for non-declaration are significant, and the inspections include X-ray and sniffer dogs.

A few things that catch first-time flyers off guard

Different rules for different countries’ immigration cards. Japan gives you a disembarkation card on the plane. The US has an ESTA system (you apply online before travel, not on the plane). Many Asian countries now use digital forms submitted via app or website before landing. Check the requirements for where you’re going and do any pre-registration in advance.

Airside vs landside. Once you go through security at your departure airport, you’re airside. Everything after that, shops, restaurants, gates, is accessible only to people with boarding passes. When you land, you’re airside until you get through immigration and customs, then you’re landside. This matters if someone is picking you up: they can only meet you in the arrivals area past customs, not at the gate.

Connections: If you have a connecting flight, your luggage is usually transferred automatically (check your booking to confirm, “through-check” means your bags go to the final destination). You’ll need to get to your next gate, which means going through security again in some airports (US connections always, some European airports, most Asian airports don’t require it if you stay airside). Build at least 90 minutes for international connections and 60 for domestic. Less than that is possible but stressful.

The first time is the most confusing. The second time you’ll move through airports like someone who knows what they’re doing. The tenth time you’ll be annoyed by how slow everyone else is moving, which means you’ve become a completely different problem.
