Airport check-in and security: a calm, simple guide

By the Safarly team · Updated 9 November 2026 · 4 min read

Most airport stress comes from small things done late. Check in online, pack hand luggage with the rules in mind, keep documents in one place and check your airport and airline rules before you leave home.

Airports feel rushed, but most problems are easy to avoid with a little preparation. This guide covers the steps from checking in to boarding. Rules differ by airline, airport and country, so use this as a checklist and confirm the details with the official sources named below.

Before you leave home

1. Read your booking. Check names match your passport exactly, and note your baggage allowance. See our guide to fare types and baggage.
2. Check in online if your airline offers it. The opening time and fees differ by airline, so read your booking e-mail. Some airlines charge for airport check-in or printing, so check before you travel.
3. Save your boarding pass. Keep a copy on your phone and, if you can, a screenshot or printout in case of a flat battery or no signal.
4. Check your passport and entry rules. Look at the official government source of your destination for visa, passport validity and any online entry form. These rules change.
5. Check the weather and airport news. Your airline and airport websites show delays or changes.

Getting there

Airlines publish a recommended arrival time, and it can differ by airport and destination. Check your airline's page or your booking e-mail and add a safety margin for traffic or trains. If you are travelling with children, older relatives or lots of bags, allow more time.

Bag drop and check-in

• Keep your passport, boarding pass and any visa or entry form together in an easy pocket.
• Put your name and a phone number inside and outside checked bags.
• Weigh your bag at home. Airlines set weight limits and may charge for excess weight.
• Keep valuables, medicines, chargers and a change of clothes in your hand luggage, not your checked bag.

Security

Security rules, especially for liquids and electronics, differ between airports and are updated from time to time. GOV.UK says the liquids rules in hand luggage depend on the airport and advises checking both your departure airport and any connecting airport. Read the current page at GOV.UK hand luggage restrictions before you pack. For flights from other countries, check that country's aviation security authority or the airport website.

• Pack liquids, gels and sprays in one place so you can take them out quickly if asked.
• Know which electronics you may need to take out of your bag at your airport.
• Empty your pockets, and wear shoes and belts that are easy to remove.
• Essential medicines usually have special rules. Check GOV.UK or your airport and carry any prescription or letter you may need.
• Some items, such as power banks and lighters, have their own airline and security rules. Check your airline's list of restricted items.

At the gate

Check the screens for your gate, as gates can change. Boarding usually closes before departure, so do not wait until the last minute. If you have a connecting flight, ask the airline whether you need to collect your bag or go through security again.

If something goes wrong

• Delay or cancellation: speak to the airline first. Your rights depend on your route and airline, so check the official rules for your journey, for example the UK Civil Aviation Authority for flights covered by UK rules.
• Missing bag: report it at the airport before you leave and keep the reference number.
• Missed flight: contact the airline straight away, and tell us if you booked through us.

Quick answers

How early should I arrive at the airport?

It varies by airline, airport and destination. Check your airline booking e-mail or website for its recommended time, and add a safety margin.

What can I take in hand luggage?

Rules vary by airport and country and change over time. Check GOV.UK hand luggage restrictions for UK airports, and your airline for its own size and weight limits.

Should I print my boarding pass?

A phone copy is accepted by many airlines, but a screenshot or printout is a useful backup. Check your airline's guidance.
