Why planning ahead matters for your airport arrival time? 

No two trips to the airport are ever quite the same. Planning ahead can help you enjoy a smooth and stress‑free airport experience.  

Arriving early gives you a buffer for the unexpected, whether longer‑than‑usual security queues or last‑minute gate changes. The time of morning, day or evening you’re travelling to the airport is a key factor to consider too.  

Also, having other things sorted in advance like travel money, eSims and airport parking will minimise further stress when you arrive at the airport ahead of your flight. For convenience, you can manage all this in the one place via the travel app.

When you plan your arrival time strategically, you’re not just avoiding the panic of a last‑minute rush. You’re also giving yourself a better chance of starting your journey calm and organised. And it means you’ve got extra time to do any last-minute airport shopping.

How early should I arrive for my flight? 

With different types of flights come various arrival time windows to follow as a rule of thumb. Depending on what type of flight catching, it’s a good idea to allocate the following amount of arrival time:

  • Domestic UK flights: Arrive 1.5 to 2 hours before departure 

  • Short haul international flights: Arrive 2 to 3 hours before departure 

  • Long haul international flights: Arrive 3 hours before departure 

This usually gives you enough breathing space to check in, get through security and reach your gate without rushing. If you’re flying at a busy time or from a new or larger airport, it’s a good idea to give yourself extra time on top.  

How early should I get to the airport for a domestic flight? 

If you’re flying within the UK, it tends to be a quicker process. You’ll still have to go through security but some airport terminals for domestic flights tend to be smaller with a shorter distance to gates.  

If you’ve checked in online and you’re travelling with hand luggage only, you may not need as much time. But remember that, if you need to check in a bag, airlines can still set firm cut off times for bag drop and boarding times. Here’s a guide on times you should keep in mind: 

  • Arrive at the airport: 90 minutes to 2 hours before departure 

  • Bag drop usually closes: 40 to 60 minutes before departure 

  • Boarding usually starts: 30 to 45 minutes before departure 

How early should I get to the airport for a short haul international flight? 

If you’re flying to Europe or nearby destinations like Africa, you’ll need to allow more time for bag drop, security and boarding so you’re not dashing from queue to queue. Here’s a guide on the times to keep in mind:

  • Arrive at the airport: 2 to 3 hours before departure 

  • Bag drop usually closes: 40 to 60 minutes before departure 

  • Boarding usually starts: 30 to 45 minutes before departure 

How early should I get to the airport for long haul international flights? 

If you’re flying on an international flight, you’ll need considerably more time. There are usually more checks, passengers and often much larger terminals to navigate. As a guideline:

  • Arrive at the airport: At least 3 hours before departure 

  • Bag drop usually closes: 40 to 60 minutes before departure 

  • Boarding usually starts: 30 to 45 minutes before departure 

Remember, some airlines open check in earlier than this, especially at major airports. It’s always worth checking your airline booking details and requirements before you travel. 

Avoid expensive rates and a rush at the airport

Things to consider when you arrive at your airport  

The timings we’ve just covered are a guideline for different types of flight. But there are a few factors that may affect how much time you want to give yourself at the airport before boarding.  

Remember, small delays can add up before you know it so having extra time planned may be wise. Here are some of the most common reasons airports take longer than expected.  

Airport size and layout 

Large airports often mean longer walks to check in desks, security, food, shopping and departure areas, and boarding gates. There may be more than one terminal or more people moving through security at the same time. This can add on a significant amount of time, especially during peak holiday season or events.

On the other hand, regional airports may be quicker due to smaller terminals and gates, but queues can still spike at busy times. 

Airline rules 

Each airline sets its own check in and bag drop rules. If you miss them, you might not be allowed to travel, even if you’re already at the airport. Don’t assume your airline requires the same as others you’ve flown with before. It’s important to check their own rules to be sure.

Time of day 

Early mornings and late afternoons are often the busiest at airports as these are peak flying times. Flying in the evening or at night tends to be quieter, meaning you should get to your gate quickly. Remember, security queues can change quickly, especially during school holidays and bank holiday weekends. 

Checked baggage 

Depending on your airline, bag drop can take time due to a busy flight or limited bag drop desks opened at any one time. If you’re bringing oversized items, sports equipment or special luggage, this can add more time at the desk.  

To avoid time delays, check which items you can take on board and what needs to be checked into the hold instead.  

Special assistance 

If you have a disability or you find moving around hard, you may need extra help at the airport. 

Try to arrive earlier than normal. This gives staff more time to support you. 

You might need help with: 

  • Checking in your bags 

  • Moving through the terminal 

  • Getting to your gate 

  • Going through security 

These steps can take longer, especially when the airport is busy. Arriving early helps you avoid rushing and missing your flight. It also makes your journey calmer and easier. 

A helpful airport checklist to help you board your flight on time 

When you arrive at the airport, it can be tempting to go straight to the shopping area or relax in a restaurant or bar. But it’s important not to lose sight of the time you have before boarding. Always plan enough time for the essentials and anything else is a bonus.  

When you first arrive, you’ll need to: 

  • Check in (if you haven’t already done it online) 
  • Drop off bags if needed 
  • Pass through security
  • Check when your gate number will show up on the board 
  • Find and plan the walking distance to your gate 
  • Board your flight 

Once you’ve planned all the essentials before you board, you might also want to: 

  • Grab food or drink 
  • Use the toilet 
  • Shop in duty free 
  • Exchange money 
  • Relax in a lounge 

How long will each airport step take before the final boarding call? 

Every airport is designed differently. Some have gates you can reach easily walking from their departure areas. Other have gates you’ll need transport to reach, like monorails. Having a rough idea of how long each step at the airport may take can make sure you’re not rushing to make a final boarding call.  

Find out how much time you should give for each, remember each airport is different so it’s always best to have extra time: 

Airport step/process  Approx timings 
Check in and bag drop
  • Online check in: Done before you arrive 

  • Check in at desk (if you prefer): Often takes between 10 and 30 minutes and over 30 minutes during peak travel times  

  • Bag drop: Often takes 15 to 30 minutes or up to and over one hour during busy peak season 

Security screening 
  • Quieter periods: Often takes 10 to 20 minutes 

  • Busier periods: Often takes 30 to 60 minutes or more for peak season or events 

Passport control 
  • UK departures: Usually quick between 5-15 minutes 

  • Other countries for departures: Sometimes involve extra checks so could take anywhere between 10 to 20 minutes or 30 to 60 minutes 


Make sure your passport’s still valid well before you travel 

Walking to the gate 
  • Smaller airports: Often 5 to 15 minutes 

  • Larger airports: Often 15 to 25 minutes or 30 minutes or more for further gates 

Boarding 
  • Boarding often starts: 30 to 60 minutes before departure 

  • Gates often closes: 15 to 20 minutes before departure 

 

Should I get travel money at the airport? 

In most cases, you shouldn’t get travel money at the airport as exchange rates and fees are often higher than you could get elsewhere. Choice of currency can also be limited, meaning the one you need might not be in stock. You could also face queues adding extra time pressure if when you arrive at the airport.  

Sorting travel money ahead of time may get you a better deal and should make airport days feel more relaxed and enjoyable. And we can help with that.

Common questions

  • No. Checking in online might save you some time and hassle but doesn’t mean you can arrive later. Remember, you still need to allow enough time to drop off any hold baggage, get through security queues and the distance walk or travel to your gate. You might also need time to pick up last-minute items at the airport. 

  • Yes, you should arrive a little bit earlier at the airport during school holidays as queues are often longer. There can also be bigger queues at weekends and for early morning departures. 

  • Airlines usually close their bag drops and boarding gates at set times. If you miss them, you may not be allowed to travel and might need to book another flight. If you missed the deadline for your bag drop and your baggage is small, you can ask the airline if you can convert it to cabin baggage.
