Do not pack flammable industrial sprays, fuel or paint as if they were toiletries.
For Aer Lingus, check the product and the airline’s current dangerous-goods conditions before placing sprays or perfume in the hold. Your ticket may not include checked baggage, and partner-operated sectors can have different baggage allowances. Keep essential medicines with you in the cabin, subject to screening.

Practical toiletries packing tips for your Aer Lingus journey:
Start with the route — Dublin, a UK departure and a North American connection can have different security procedures. Aer Lingus’s 10kg bag entitlement and whether it travels in the cabin are fare matters, separate from the liquids check.
Follow the airline guidance — Aer Lingus directs passengers to the EU security rules for cabin liquids, gels and aerosols; under the standard EU process, ordinary containers are limited to 100ml and packed in a transparent resealable 1-litre bag.
Prepare the liquids bag — Prepare one transparent resealable bag of up to 1 litre at an EU checkpoint using the standard process. Follow the actual airport’s instructions if screening arrangements differ.
Keep medical items accessible — Essential medicines, baby food or milk and special dietary liquids can be handled as exceptions at EU/UK screening, with separate inspection or evidence; check the exact airport.
Read the printed capacity — At a standard 100ml checkpoint, the container size matters even if a larger bottle is almost empty.
Count pastes and sprays — Toothpaste, cream, gel, roll-on deodorant, mascara and permitted aerosols can all count as liquids.
Protect duty-free purchases — Keep qualifying purchases in the sealed security bag with the receipt and check transfer screening before purchase.
Consider solid alternatives — Solid soap and solid deodorant can free space in the liquids bag; always check an unusual product.
Secure aerosol valves — Use protective caps and check that the particular personal-care spray is permitted in the cabin or hold.
Separate larger products — Place larger ordinary toiletries in checked baggage when included, subject to the product’s dangerous-goods rules.
Check your airport’s liquids rules before flying Aer Lingus
Airport security, the airline’s carriage rules and dangerous-goods restrictions are separate checks. Aer Lingus directs passengers to the EU security rules for cabin liquids, gels and aerosols; under the standard EU process, ordinary containers are limited to 100ml and packed in a transparent resealable 1-litre bag.
For UK departures, most UK airports ordinary liquids remain limited to containers of 100ml, while some airports permit containers up to 2 litres. Check your exact departure airport, any transfer checkpoint and the return airport; one airport’s process does not govern the whole itinerary. Dublin, a UK departure and a North American connection can have different security procedures. Aer Lingus’s 10kg bag entitlement and whether it travels in the cabin are fare matters, separate from the liquids check. Essential medicines, baby food or milk and special dietary liquids can be handled as exceptions at EU/UK screening, with separate inspection or evidence; check the exact airport.
How common toiletries are treated at airport security
Many everyday toiletries are treated as liquids, gels, pastes or aerosols when you pass through airport security. This isn't determined by the airline you're flying with, and the exact restrictions can vary depending on the security rules and screening equipment used at your departure airport. Here's how some of the most commonly packed toiletries are generally treated:
Deodorant
Roll-on and aerosol deodorants are generally treated as liquids for airport-security purposes. Solid stick deodorants are normally treated differently and can be a useful option if you want to reduce the number of items in your liquids bag.
Toothpaste
Toothpaste counts as a paste and is treated as a liquid at airport security. Where the traditional 100ml restrictions apply, the size of the toothpaste container therefore needs to comply with the applicable liquids limit.
Shampoo and conditioner
Shampoo and liquid conditioner are treated as liquids. This also applies to similar hair products such as gels, serums and liquid styling products. Solid shampoo and conditioner bars are generally not treated as liquids.
Shaving foam and gel
Shaving gels and foams are subject to liquid-security requirements. Aerosol shaving foam may also be subject to dangerous-goods restrictions, so larger products need particular consideration if you're packing them for a flight.
Hairspray
Hairspray is an aerosol and is treated as a liquid for cabin-security purposes. Aerosol toiletries can also be subject to airline dangerous-goods limits, so check your airline's requirements as well as the security rules at your departure airport.
Sun cream
Sun creams, lotions, gels and sprays are treated as liquids for cabin-security purposes. This includes products such as after-sun lotion and moisturising sun protection. Solid sun-protection products are generally easier to accommodate when travelling with limited liquid allowance.
Make-up and cosmetics
Liquid foundation, mascara, creams, gels, lip gloss and similar products are generally treated as liquids. Solid and powder cosmetics are generally not subject to the same liquid restrictions, although they will still pass through normal security screening.
Perfume and aftershave
Perfume, aftershave and other liquid fragrances are treated as liquids at airport security. They may also fall within dangerous-goods limits applying to toiletry and medicinal articles, particularly when larger quantities are carried.
Remember: airport-security procedures are changing as new screening equipment is introduced. Some airports may allow larger liquid containers or have different requirements for removing liquids from your cabin bag. Always check the current rules for the airport you're departing from — and any airport you'll use on a connecting or return journey — before you travel.
