Twenty hours in a new city. The galley talk says there's a rooftop bar worth the walk, a spot for a proper massage, a café that offers crew a discount. A month later ? Gone. LayoverLoop makes sure those tips survive the trip. It's a crew-built city guide for 160+ layover destinations (and you can request your destinations too!), filled by real pilots and cabin crew who actually landed there. Every tip, every rating, every hidden gem — from people who've been in your shoes to roam the city. ============== WHAT YOU'LL FIND ============== ■ 160+ cities, crew-tested tips Where to eat, drink, sleep, sweat, and unwind — sorted by city, category, proximity or region. First time in Doha or fiftieth in Bangkok, there's always something new waiting. ■ Upvote & comment The good stuff floats to the top. Drop a comment, update a tip, share your find. It's a living guide, not a static list. ■ Crew-validated bargains We hunt down the deals that actually hold up: crew discounts, happy-hour gems, budget-friendly spots that don't feel budget. If it's in LayoverLoop, a crew member actually checked it out and vouched for it. ■ Your eSIM, at competitive prices Purchase an eSIM directly for your layover city — pick a plan, pay securely, and install it from a QR code or one tap, all without leaving LayoverLoop. Choose country-specific plans or a Global plan for multi-stop trips. Track your remaining data and validity, and request a cancellation & refund if you change your mind. ■ The essentials, one tap Currency converter, plug types, water safety, eSIM deals, emergency numbers, local experiences. All the boring-but-critical stuff, handled. ■ Map view Every spot pinned, so you can see what's actually near your hotel and plan at a glance. ■ Bookmarks & social Save the cities and spots you love. Peek at what your crew friends have bookmarked too. ■ Search & filter Rooftop bar in Brussels? Gym in Melbourne? Veggie spot in Boston? Search by city, category, or keyword and you're there. ============= BUILT DIFFERENT ============= LayoverLoop is independent — not tied to any airline, union, or travel company. Just a crew member who wanted this to exist. ■ Free forever. No subscriptions, no paywalls. Just use it. Register only if you decide to contribute and make everyone's layover better. ■ Confidential. Data stored is encrypted and unreadable. No tracking beyond what makes the app work. ■ No work ID. No work email. No airline sign-in. Browse, save, and contribute as an assigned anonymous username — nothing ties you to your company or real identity. ========= THE VISION ========= Think of LayoverLoop as our shared crew memory. The ramen shop in Osaka. The rooftop pool in Johannesburg. The barbershop in Istanbul that charges almost nothing. The café in Lisbon where the owner gives crew a discount. All the tips we trade in the galley, in the van, in the hotel lobby — collected in one place so they never get lost. Replace your Notes app or your secret layover notebook. If you've got a local secret in any layover city, drop it in. The next crew member landing there for the first time will thank you. Built by crew. For crew. Welcome to LayoverLoop.
