IGA Lounge

55,000 sqft, 600 seats, and free showers: this is iGA.

The iGA Lounge in IST Main Terminal sits above the A and B gates, up the escalators by the Ralph Lauren store and left after security, and functions as the contract hub for everyone not on Turkish Airlines. It runs 24 hours a day, so overnight layovers and 03:00 departures all funnel here, which is why reception has a maze of tensabarriers and boarding-pass scanners built for serious throughput.

Access is straightforward: pay at the door for a day pass at €115 per person, or come in on Priority Pass, DragonPass, or an eligible airline invite like BA business/elite. Day-pass guests reportedly get up to 6 hours, while Priority Pass and similar cards are capped around 3 hours, so don’t roll in 8 hours early expecting to camp. BA passengers can often scan boarding passes directly at the turnstiles and skip the general queue.

Food and drink lean mass-catering but better than most US contract lounges: hot dishes, salads, desserts, and self-serve soft drinks dotted across multiple stations so you’re not stuck at one bar. Alcohol usually means Efes on tap plus mid-shelf vodka, gin, whisky, and basic wines, all self-pour. You come here to graze and refill on your own schedule, not for a chef tasting menu.

Showers are a standout because they’re free, inside the lounge, and consistently reviewed as clean and private, which matters after a 10‑hour sector into Istanbul. The lounge’s sheer 55,000‑sqft footprint helps keep noise tolerable, and there are pockets of semi-quiet seating if you walk deeper into the far corners away from reception and buffet lines.

There’s also a complimentary massage corner offering head-and-shoulder sessions roughly 08:00–17:00, Tuesday to Saturday, though several flyers report turning up during that window and finding it closed or unstaffed. Treat it as a nice bonus if it’s running, not something to plan your whole layover around, especially during the evening departure banks.

Watch out for peak-time crowding: multiple reviews say the 600-person space can still feel packed during long-haul waves, and the entrance queue can snake back through those tensabarriers. Regulars with Priority Pass or BA status often time their visit outside the late-evening rush, eat, shower, maybe nap, and then bail to the gate once the line builds.

Practical play: on a long layover, pay the €115 only if you’ll actually use the full 6-hour window to shower, eat twice, and rest; otherwise, time a 3-hour Priority Pass visit for a quick meal plus shower, then grab a quieter seat near your A or B gate.
