Aer Lingus Promo Codes — 25% Off

It's totally free and happens automatically when you create an Aer Lingus account. You'll start at Green tier right away and begin earning Avios on your first flight. Just sign up online or through their app and you're in.

Yep, gift vouchers work for flights anywhere in their network. Just remember they can only be used in the currency you bought them in, and the recipient's name has to match their passport exactly for security reasons.

Think of Avios as your spending money for reward flights and upgrades, while Tier Credits determine your membership level. You earn both when you fly, but Tier Credits reset every year while Avios stick around as long as you have account activity every 36 months.

App deals vary by route and season, but they're available across their whole network including European and North American destinations. Download the app to see what's currently available — these deals change regularly and you won't find them on the website.

You can get voucher refunds if you book these fare types:

• AerSpace
• Smart
• Advantage
• Flex
• Business
• Business Flex

Basic Saver and Plus fares to Europe, and Saver fares to North America don't qualify. Just apply at least 2 hours before departure.

Avios don't expire as long as you have some account activity every 36 months. This includes earning or spending Avios through flights, partner purchases, or online shopping. Even tiny transactions keep your account active and your points safe.

Yes, you can change destinations once within the same region using their Manage Booking tool online. So you could switch from London to Paris, but not from London to New York. Change fees and fare differences might apply depending on your ticket type.

Silver members get some pretty sweet perks:

• 25% extra Avios on all flights
• Dedicated check-in areas
• Fast Track Security
• Priority boarding
• Lounge access
• One free 10kg carry-on bag

You'll reach Silver by earning 301 Tier Credits through flights and qualifying activities.

Vacation packages bundle flights and hotels at discounted rates, often saving up to $425 compared to booking separately. You'll also earn Avios on the flight portion and can apply the same change policies as regular flight bookings for added flexibility.

First, make sure you're booking directly through Aer Lingus's website or app — codes don't work on third-party sites. Then check these common issues:

• Route restrictions (some codes only work for specific destinations)
• Minimum spend requirements
• Travel date limitations
• Fare type restrictions

If everything looks right but it's still not working, contact their customer service team.
