Dublin's 51st&Green lounge is back after a six-month refit, and the new Phoenix Lounge doubles T1 seating

News and analysis · Sources checked October 6, 2026.

Dublin Airport has finished its lounge overhaul. The 51st&Green Lounge, the only lounge beyond US Preclearance in Terminal 2, reopened on April 1, 2026 after about six months closed for a full refurbishment and extension, Business Traveller reported. Two weeks later, on April 16, the new two-level Phoenix Lounge opened in Terminal 1 with more than 300 seats, roughly double the old T1 Lounge it replaced, per Travel Extra. Both have now had a full summer of traffic.

What you pay and who gets in free#

51st&Green is open 07:15 to 17:00 daily, matching the US departure bank, with a two-hour maximum stay. Dublin Airport now lists €45 online and €55 at the door, up from the €42 and €50 quoted at reopening. Business class passengers and eligible elites on Aer Lingus, American, Delta and United get in free. Two alcoholic drinks per person are included; there is a central bar with Guinness on draft, a hot and cold buffet, workstations and an accessible shower.

The Phoenix Lounge runs 04:00 to 21:00, costs from €35 online or more at reception, and also caps visits at two hours. It accepts DragonPass but is not in Priority Pass, which means the Liffey Lounge in Terminal 2 remains the Priority Pass option. The Martello Lounge in T2 and the Aer Lingus Lounge round out the airport.

Our take#

Both lounges are better than what they replaced, and Dublin now has a coherent set of airport-run lounges rather than a collection of tired rooms. The two-hour cap is the catch. For a transatlantic passenger who has cleared two sets of security and preclearance, two hours is tight, and at €55 walk-up it is one of the more expensive pay-in lounges in Europe for the time allowed. Book online, arrive with your preclearance done, and treat it as a meal and a shower rather than a place to spend the afternoon.

Putting this into practice#

The names I'd check against the actual boarding pass include 51st&Green, Phoenix Lounge. I would start with the terminal and the time available after security. That turns a directory into a realistic shortlist. A lounge can be excellent and still be a poor choice for this departure if reaching it uses most of the waiting time. The location notes above should do as much work as the overall score.

The access check comes next. I'd identify the exact card, membership, status or ticket being used and read the conditions for that route into the lounge. A lounge appearing on a card's map is a starting point for that check. It is not a reason to assume every fare, guest or departure will qualify in the same way.

I would decide what I want from the stop before comparing amenities. For a meal, the food available during the actual visit matters. For work, I'd look for a suitable seat and power. For a short connection, simply finding a comfortable place near the gate may be the better result. There is little value in an amenity I cannot use.

The trade-offs I would check#

Traveling with someone else changes the calculation. I'd check the party's eligibility together, including any guest charge, rather than discover at reception that only one person is covered. A paid visit needs to make sense for the whole group and the time left. I would compare that total with a meal or a quieter seat elsewhere in the terminal.
