The Flight Review: Aer Lingus Business Class Airbus A321
Luxury Reviews Says 8/10
Overnight transatlantic on a single-aisle jet with flat-bed seats — is a few hours’ sleep worth the upgrade?
The Airline
This is the return overnight flight that Luxury Reviews covered here.
Aer Lingus uses the single-aisle A321—traditionally a short-haul workhorse—on an expanding roster of transatlantic routes. This lets them add extra frequencies on popular paths or launch new “long and thin” services, like Dublin to Nashville.
The Vibe and Who Are You Likely To See On Board
The flight was mostly filled with North American tourists eager to trace their Irish roots, alongside some passengers connecting onward through the Aer Lingus European network.
The First Impression 8/10
Aer Lingus Business Class check-in area is discreet rather than flashy—no red carpets, just a friendly welcome and swift service. With only 16 Business Class seats on this flight, the process feels refreshingly quick and efficient.
The Fast Track 10/10
TSA PreCheck and general security are conveniently close to the Aer Lingus check-in, and I was through in just five minutes—speedy and hassle-free.
The Lounge 8/10
Aer Lingus Business Class passengers can access the British Airways Lounge at Washington Dulles—a decent spot to wait for your flight. You can find the full Luxury Reviews take on this lounge here. Honestly, lounges these days often feel overcrowded, with lackluster food and little sense of exclusivity. At least this one is divided into different zones, which helps keep things from feeling too chaotic.
The Priority Boarding 7/10
Business Class passengers enjoy priority boarding through a dedicated lane—until you realise the drawback of a single-aisle jet. Everyone boards at the front door, so while you get to step on first, the entire plane boards behind you, leading to inevitable aisle congestion. Plus, no pre-departure drinks or crew introductions here. You might be better off enjoying that champagne in the lounge until most passengers have boarded.
The Seat And Cabin 7/10
The seat is an older generation of business class design—no sliding doors or giant HD screens here. Given that Aer Lingus flights, like Boston to Shannon, are relatively short, the seat comfort matters less than on those marathon overnight hauls.
It reclines smoothly from upright to fully flat and includes a massage feature—though it’s more novelty than relief. Power points are thoughtfully provided. Overall, it’s comfortable enough for the flight durations it serves. There are definitely better seats out there, but worse ones too.
The cabin layout mixes pairs with single ‘throne’ seats. Flying solo? Go for a throne—otherwise, privacy is basically off the menu.
With congested aisles causing boarding hiccups, you’ll find a menu and amenity kit waiting at your seat—little perks to ease you in while the chaos settles.
The Amenities 8/10
Aer Lingus doesn’t provide pyjamas or sleepwear, but Business Class passengers do get a simple amenity kit featuring a few products from Irish skincare brand Jo Browne. Given the relatively short flight times, it’s perfectly adequate. Plus, complimentary in-flight Wi-Fi for the entire journey is a welcome touch—generous compared to many competitors on the same route.
The Service 10/10
As you expect from a country known for its warm welcome, service was good. The flight manager took care of the Business Class cabin for all 16 passengers. Service was genuinely personal and at a good pace. Drink top ups were also many and generous, another Irish tradition. If you had chosen to go to sleep then the cabin environment was calm enough to allow this. Bigger Business Class cabins can be chaotic for the first couple of hours so this is a small cabin win.
The Dining 9/10
I wasn’t expecting a great deal to be offered on this short overnight flight. Yet, I was pleasantly surprised. There was a full three course dinner and breakfast available, as well as quicker express options. A breakfast card can be filled in for the morning. It also holds details of the arrivals lounge breakfast and showers option.
Aer Lingus manage to serve hot soup. A small point but it doesn’t seem possible on many other airlines. The bread roll was cold though and dessert disappointing. Aer Lingus desserts just taste cheap and don’t pass the critical ‘is it worth the calories?’ test.
Breakfast can also suit your appetite and rest plans. There were only a few hours between dinner and breakfast. I skipped the famous Aer Lingus bacon roll that was also available.
The Entertainment 6/10
It’s great that Aer Lingus include complimentary internet access. Their inflight entertainment is also perfectly acceptable for these flights, especially on this overnight flight. TV screens aren’t the biggest but the software has been updated and the system is responsive.
The noise-cancelling headsets in Business Class are a definite weak spot. Tinny, uncomfortable, and barely noise-cancelling, they feel like an afterthought—and let down an otherwise decent entertainment system.
The Attention To Detail 8/10
The dinner menu proudly highlighted its melatonin-rich ingredients—a thoughtful nod to those chasing sleep on short overnight hops. It’s a clever touch, even if the science is up for debate. More impressively, Aer Lingus offers flexible dining options like an express meal onboard and breakfast at the arrivals lounge, giving passengers every chance to maximise rest.
Irish touches continue in the details, with VOYA products in the washrooms and Jo Browne items in the amenity kits. It’s a subtle but thoughtful welcome to the Emerald Isle—and a nice reminder of the airline’s roots.
The Verdict. Is It Worth It?
Yes. Aer Lingus can offer excellent value—especially when fares undercut the big players. This was a solid flight: decent dining, a comfortable (if unflashy) seat, and genuinely warm Irish service that adds a human touch. It’s a charming and relaxed way to cross the Atlantic, even if the glamour is dialled down.
Fly This For Good food, good service and good options to work, eat or sleep.
Don’t Fly This For Fancy suites with doors and the latest Cinematic technology. Or desserts worthy of a Parisian patisserie.
