Aegean Airlines Check-In: Online, Airport & Deadlines

Checking in for your Aegean Airlines (A3) flight is straightforward, but strict timing rules apply depending on your departure airport. Aegean Airlines online check-in opens 48 hours before scheduled departure. Depending on where you are flying from, online and airport check-in generally close between 30 and 60 minutes before your flight takes off.

If you have checked bags, you must drop them off before the check-in counter closes. At Athens International Airport (ATH), all passengers checking bags must use the self-service baggage quickdrop-off system.

Here is the complete guide to checking in, getting your boarding pass, and dropping off your luggage for your Aegean Airlines or Olympic Air flight.

How to Check In Online for Aegean Airlines

Checking in online via the website or the official Aegean Airlines app is the fastest way to get your boarding pass.

Step-by-Step Online Check-In:

1. Open the official Aegean Airlines website (aegeanair.com) or open the Aegean app.
2. Navigate to the Check-in tab.
3. Enter your Booking Reference (PNR) (a 6-character alphanumeric code found in your confirmation email) and your Last Name.
4. Select the passengers you wish to check in.
5. Choose or confirm your seat. If you booked a Light fare, a seat is randomly assigned for free, but you can pay to select a preferred seat, or manage your booking ahead of time.
6. Add any extra baggage, fast-track security, or other travel add-ons if needed.
7. Confirm your travel documents (passport or national ID card).
8. Download your mobile boarding pass or opt to receive it via email to print at home.

[!NOTE] If you are traveling on a Light fare and overhead cabin storage is full, you may be asked to check your carry-on bag for free at the boarding gate.

Aegean Airlines Check-In Times & Deadlines

Aegean Airlines enforces strict deadlines for check-in and boarding. Missing these deadlines will result in denied boarding and the potential loss of your seat.

• Online Check-In Opens: 48 hours before scheduled departure.
• Online Check-In Closes: 30 to 60 minutes before departure, depending strictly on the departure airport.
• Boarding Gate Opens: Varies by airport, usually 40–45 minutes before departure.
• Boarding Gate Closes: Passengers are generally advised to be at the gate at least 30 minutes before departure. At Athens International Airport (ATH), the gate closes strictly 15 minutes prior to departure.

Check-in Closure Times by Airport (Examples)

Aegean’s minimum check-in closure times apply to web check-in, mobile check-in, kiosks, and baggage drop counters. Here are the deadlines for several major airports across the network:

Always verify your specific airport's check-in closure time directly on the Aegean Airlines website, as these deadlines are subject to operational changes.

Airport Check-In and Baggage Drop

If you prefer to check in at the airport or need to drop off checked luggage, proceed to the Aegean Airlines departures area.

If you only have carry-on baggage:

If you successfully checked in online and have your mobile or printed boarding pass, you can bypass the check-in counters and head directly to airport security screening and your departure gate.

If you have checked baggage:

After checking in online, you must print your bag tags and hand over your luggage at the designated Baggage Drop-Off desks before the check-in deadline. Review your Aegean Airlines checked baggage allowance before heading to the airport.

• Athens International Airport Exception: All passengers departing from Athens with checked bags are required to use the Self-service baggage quickdrop-off system.
• Electronic Bag Tag: Aegean supports electronic bag tags. If you own a compatible bag tag device, you can activate it via NFC using the Aegean app during mobile check-in and take your luggage straight to the automated drop-off belt.

Boarding Pass Options

Aegean Airlines offers multiple boarding pass formats to fit your travel style:

• Mobile Boarding Pass: A 2D barcode delivered to your smartphone via the Aegean app, Apple Wallet, or Google Wallet. This format is accepted at most major European airports.
• Printed Boarding Pass: You can print your boarding pass on standard paper at home after checking in via the website.
• Kiosk / Counter Printing: If your phone battery runs out or you cannot print at home, you can print a physical pass at a self-service kiosk or an Aegean desk before the check-in deadline.

[!IMPORTANT] A few airports outside the Schengen area do not support mobile boarding passes (2D barcodes) at security checkpoints. If you are departing from an airport that does not support them, you will receive a "Check-in Confirmation" on your mobile device instead. You must present this confirmation at an airport kiosk or ticket counter to receive a standard paper boarding pass.

Who Cannot Check In Online?

While most passengers can use the online system, Aegean and Olympic Air restrict online check-in for certain travelers who require physical document verification or special assistance at the airport. You must check in at the airport counter if you are:

• A minor (under 16 years old) traveling alone (Unaccompanied Minor).
• A minor (under 16) traveling on a separate booking from the accompanying adult.
• A passenger who has requested medical assistance or an airport wheelchair.
• A passenger traveling with a pet or emotional support animal in the cabin or hold.
• Traveling on a booking where the previous flight was not operated by Aegean or Olympic Air.
• Traveling in a group booking of 10 or more people.
• A passenger with a ticket requiring additional ancillary payment at the airport.

Connecting and Codeshare Flights

If your journey includes multiple flights, the check-in rules depend on which airline operates the first leg of your trip:

• First flight operated by Aegean / Olympic Air: You can check in for your entire journey (including connections operated by Star Alliance partners) via the Aegean website, provided onward flights depart within 24 hours. Your baggage will typically be checked through to your final destination.
• Codeshare flights (First flight operated by another airline): If your flight was booked through Aegean but is operated by a partner airline (e.g., Lufthansa, Swiss, TAP Air Portugal), you must check in using the operating carrier's website, app, or airport counters. Aegean’s online check-in system cannot generate boarding passes for flights operated by other carriers.

International Flights & Document Verification

When flying internationally, especially outside the Schengen Area, you must carry a valid passport and any necessary visas or entry authorizations.

Even if you check in online, Aegean Airlines may require you to undergo a physical document check at the check-in counter or the boarding gate before you are allowed to board. Have your passport, visa, and return ticket readily available. Ensure your passport meets the validity requirements (usually 3 to 6 months beyond your travel dates) for your destination country.

Online Check-In Not Working? Troubleshooting

If you encounter an error while trying to check in online for your Aegean flight, verify the following common issues:

1. You are too early: Online check-in opens exactly 48 hours before departure.
2. You are too late: The check-in window closes 30 to 60 minutes before departure depending on the airport.
3. You are on a codeshare flight: If another airline is operating the flight, go to the operating carrier's website to check in.
4. Special assistance requested: If you added a pet, requested a wheelchair, or booked an unaccompanied minor, the system blocks online check-in. Proceed to the airport counter.
5. Name mismatch: Ensure the last name entered exactly matches the name on your booking confirmation (without spaces or extra titles, unless booked that way).
6. Operational changes: Always check your flight status if you suspect a schedule alteration or aircraft swap.

If technical issues persist, arrive at the airport early and complete check-in at an Aegean counter or self-service kiosk.

What Happens If You Miss the Check-In Deadline?

If you fail to check in online or at the airport before the final closure time (e.g., 40 minutes before an Athens departure), Aegean Airlines will cancel your seat assignment, and you will be denied boarding.

If you miss the deadline:

• Immediately locate an Aegean Airlines ticket desk or customer service counter at the airport.
• Depending on your fare type (e.g., Light, Flex, ComfortFlex), you may be able to pay a change fee to be rebooked on the next available flight.
• If you hold a non-flexible ticket, missing the check-in deadline is typically treated as a "no-show," and you may lose the value of your ticket entirely.
