How Early Should You Arrive at Dublin Airport?
Flying from Dublin Airport for a holiday? Knowing when to arrive can help you avoid unnecessary queues and make sure you have enough time for check in, bag drop, security and boarding.
The amount of time you need can depend on your airline, destination, whether you’re checking luggage and how busy Dublin Airport is when you travel.
Quick Answer
For most short haul flights from Dublin Airport, aim to arrive around 2 hours before departure. For long haul flights, allow around 3 hours.
If you’re checking luggage, travelling with children or flying during a busy holiday period, consider allowing additional time.
Your airline’s own check in, bag drop and boarding deadlines should always take priority.

How Early Should You Arrive at Dublin Airport?
For many passengers taking a short haul flight from Dublin Airport, arriving around two hours before departure is a sensible starting point.
For long haul flights, allowing around three hours gives you more time to complete the various stages of your journey before boarding.
However, there isn’t a single arrival time that works for every passenger.
Someone travelling alone with hand luggage and already checked in online may need less time than a family travelling during the summer holidays with several bags to check in.
The amount of time you need can depend on:
- Your airline.
- Your destination.
- Whether you have checked baggage.
- Whether you’ve checked in online.
- The time of day.
- How busy Dublin Airport is.
- Whether you’re travelling during a school holiday or other busy period.
The two hour and three hour recommendations should therefore be treated as general guidelines rather than guarantees.
When Does Check In Open at Dublin Airport?
There isn’t one standard check in opening time for every flight from Dublin Airport.
Airport check in times are determined by the individual airline and can vary depending on the flight and destination.
It’s also important to distinguish between online check in and airport check in.
Online check in can open well before you travel to the airport, while airport check in desks only become available closer to the departure time.
If you’ve already checked in online but have checked luggage, you’ll normally still need to use your airline’s bag drop facilities.
For this reason, checking in online before travelling doesn’t necessarily mean you can arrive at Dublin Airport immediately before your flight. You still need to allow time for bag drop, security and getting to your gate.
When Does Bag Drop Open at Dublin Airport?
Bag drop opening times depend on the airline you’re travelling with.
This means arriving extremely early doesn’t necessarily mean you’ll be able to immediately drop off your luggage.
For example, Ryanair states that its check in and bag drop desks open at the latest 2 hours before scheduled departure.
Aer Lingus generally opens airport check in 2 hours 30 minutes before departure, although some destinations have different arrangements.
If you’re planning to arrive particularly early, check your airline’s requirements before travelling.
When Does Bag Drop Close at Dublin Airport?
Knowing when bag drop closes is particularly important.
Airlines have cut off times for check in and baggage and arriving after the deadline could mean you’re unable to check your luggage onto the flight.
Ryanair
Ryanair’s terms state that its check in desks currently close strictly 40 minutes before scheduled departure, unless passengers are notified otherwise.
However, Ryanair has also stated that for passengers flying from 10 November 2026 onwards, its check in desks will close strictly 60 minutes before scheduled departure, unless passengers are notified otherwise.
This means Ryanair passengers travelling from Dublin should check the latest requirements applying to their particular flight, especially for travel from November 2026 onwards.
Aer Lingus
Aer Lingus generally closes airport check in 45 minutes before departure, although some destinations have a 60 minute closing time.
These deadlines mean you shouldn’t plan to arrive at Dublin Airport shortly before your flight simply because the flight itself doesn’t depart for another hour.
You need to allow time to complete check in or bag drop, pass through security and reach your gate.
How Early Should You Arrive for a Ryanair Flight From Dublin?
Ryanair is a popular choice for Irish travellers flying from Dublin to destinations across Europe.
Ryanair states that its check in and bag drop desks open at the latest two hours before scheduled departure and close strictly 40 minutes before departure, unless otherwise notified.
For example, if your Ryanair flight from Dublin departs at 10:00am:
- Check in and bag drop open at the latest by 8:00am.
- Check in and bag drop close at 9:20am.
- You then need enough time to pass through security and reach your gate.
Ryanair states that passengers who do not check in by the closing time may be denied boarding without a refund.
How early can I check in with Ryanair?
Ryanair allows passengers to check in online before travelling to Dublin Airport.
If you’re travelling with checked luggage, however, you’ll still need to allow enough time to use the bag drop facilities before they close.
Checking in online before leaving home can make the airport process more straightforward, but it doesn’t remove the need to meet the baggage drop deadline if you have a suitcase to check in.
How Early Should You Arrive for an Aer Lingus Flight From Dublin?
Aer Lingus has different check in arrangements depending on your flight and destination.
For its standard airport check in arrangements, Aer Lingus states that airport check in opens 2 hours 30 minutes before departure.
For certain destinations, airport check in opens 3 hours before departure.
Airport check in generally closes 45 minutes before departure, although some destinations have a 60 minute closing time.
If you’re flying Aer Lingus from Dublin, check the requirements for your particular flight rather than relying solely on a general two hour recommendation.
Aer Lingus online check in
Aer Lingus also offers online check in.
For flights departing Ireland, the UK and Amsterdam, online check in generally opens 48 hours before departure and closes 60 minutes before departure.
Some fares allow passengers to check in earlier, depending on the booking and whether a seat has been purchased.
Your individual booking should always be checked for the applicable arrangements.
Is 2 Hours Enough to Get Through Dublin Airport?
For many short haul flights from Dublin, arriving two hours before departure can be enough time to complete the airport process.
However, there is no guarantee that you’ll be through Dublin Airport within two hours.
After arriving, you may need to:
- Check in if you haven’t already done so.
- Drop off checked luggage.
- Pass through security.
- Walk to your departure area.
- Find your gate.
- Be ready for boarding before the scheduled departure time.
Security queues and other delays can vary throughout the day.
Someone travelling with hand luggage and already checked in online may have considerably fewer steps to complete than a family checking several bags.
For this reason, two hours should be viewed as a general arrival guideline rather than a guarantee.
How Long Does Dublin Airport Security Take?
Security is one of the biggest variables when deciding how early to arrive.
There isn’t one fixed security waiting time at Dublin Airport because queues can change throughout the day.
Passenger numbers, flight schedules and busy travel periods can all affect how quickly you move through the airport.
This is particularly relevant when travelling during popular Irish holiday periods, when more passengers may be heading abroad from Dublin.
It’s therefore sensible to leave enough time between arriving at the airport and your airline’s boarding deadline rather than assuming security will be quick.
Flying From Dublin to Spain, Portugal or Greece?
Dublin is an important departure point for Irish travellers heading to popular European holiday destinations. Dublin is also a popular departure point for all inclusive holidays from Dublin, particularly to destinations such as Spain, the Canary Islands, Portugal and Greece.
Short haul holiday destinations from Dublin include places such as:
- Spain
- Portugal
- Greece
- The Canary Islands
- The Balearic Islands
- Turkey
If you’re flying from Dublin to a European sunshine destination, arriving around two hours before departure is a useful general starting point.
For example, someone travelling from Dublin to Malaga, Alicante, Tenerife, Faro, Mallorca or one of the Greek islands may be taking a short haul holiday flight.
However, your individual circumstances still matter.
A passenger travelling alone with hand luggage may need considerably less time at the airport than a family travelling with several checked bags during the summer holidays.
When Should You Arrive at Dublin Airport During School Holidays?
If you’re travelling from Dublin during an Irish school holiday, allowing additional time can be sensible.
Popular busy periods can include:
- Summer school holidays.
- Easter holidays.
- Christmas and New Year.
- Bank holiday weekends.
- Other popular holiday periods.
Families can have additional luggage, pushchairs and other items to deal with, so the airport process may take longer than it does for an individual travelling with hand luggage.
If you’re travelling during a particularly busy period, arriving earlier gives you a larger margin for unexpected queues.
What If You're Travelling With Checked Luggage?
If you’re checking luggage, don’t simply work backwards from your flight departure time.
You also need to consider your airline’s bag drop closing time.
For example, a Ryanair passenger with a 10:00am flight needs to have completed the airline’s check in and bag drop process before the applicable cut off.
For flights before 10 November 2026, Ryanair’s stated airport check in desk closing time is 40 minutes before departure unless otherwise notified. For flights from 10 November 2026 onwards, the stated closing time is 60 minutes before departure unless otherwise notified.
The same principle applies to Aer Lingus and other airlines: check the specific baggage deadline for your flight and allow enough time to complete the process.
What If You're Travelling With Hand Luggage Only?
- Getting into the airport.
- Security.
- Walking to your departure area.
- Finding your gate.
- Boarding.
What Happens If You Arrive Too Late at Dublin Airport?
Arriving shortly before departure leaves very little margin for delays.
You could miss:
- Check in.
- Bag drop.
- Security.
- Boarding.
Importantly, the flight’s departure time isn’t the only deadline you need to consider.
For example, Ryanair’s airport check in desk deadline is currently 40 minutes before departure, but this changes to 60 minutes for flights from 10 November 2026 onwards, unless passengers are notified otherwise.
Missing the applicable check in deadline can result in being denied boarding.
This is why it’s better to plan your journey around the airline’s deadlines rather than simply aiming to arrive shortly before the flight.
