Iberia Premium Lounge Velázquez

One long rectangle of lounge stretches almost the full T4S pier

Iberia Premium Lounge Velázquez sits in T4S non‑Schengen on Level 1 in zone RSU, after passport control and the underground train from main T4. It runs along the window line for what feels like several hundred meters, so picking your zone matters. The lounge stays open 24 hours, serving Iberia and oneworld premium passengers and status holders heading to long‑haul and other non‑Schengen departures.

You enter from the central T4S concourse and go down one level past the duty‑free and shops to find the reception desk. Access is for oneworld business/first and Sapphire/Emerald, plus eligible Iberia customers on T4S flights. If your boarding pass shows a Schengen gate in T4 proper, this lounge in T4S will not work for you; check your gate letter before riding the train across.

The key quirk: the main hot and cold buffet and full bar sit in one far corner, while the rest of the lounge mainly has drinks and light snacks. FlyerTalk reports from 2023 call the buffet “very decent,” with proper hot dishes and salads, but you need to sit within a few rows of that area if you care about food. From the opposite end, expect a several‑minute walk each time you want more than chips or cookies.

Alcohol options center on the “Rincón del Vino” wine corner, a dedicated self‑pour section with Spanish wines featured in trip reports and photo sets. The main bar near the buffet also serves spirits and beer, typically included with lounge entry. Coffee machines and soft drinks appear at multiple points along the lounge, so you can grab basic drinks without hiking back to the buffet corner.

Facilities go beyond food: there are showers near the rest areas, a children’s playroom, several relaxation rooms, and a separate evening “courtesy restaurant” arrangement for some Iberia premium passengers. Regulars plan a full routine here—shower, proper meal, then board long‑haul flights like IB6403 or BA flights to the Americas ready to sleep. All of this runs 24/7, matching Iberia’s late‑night and early‑morning bank.

Wi‑Fi is technically complimentary but frequently described as finicky, with login pages timing out. Many travelers fall back to mobile data, especially in busier evening periods around 20:00–22:00 when multiple transatlantic departures leave. Power outlets run along many seating areas, but bring a Type C or F plug; Spanish sockets won’t accept UK three‑pin plugs directly.

What regulars do: they grab a seat close to the buffet corner, hit the showers early in the evening wave before the 22:00 rush, and eat a real dinner here instead of on the aircraft. One practical tip: check your T4S gate first, then walk toward that side of the lounge and pick a seat within line‑of‑sight of the main buffet to cut down on back‑and‑forth walks.
