Here’s how I got a lunch & shower at Changi Lounge, before passport control: Used the Visa Airport Companion app that came with my credit card. Scanned the QR, got a voucher for: – One hot meal (I chose the vegan option) – Unlimited drinks – A private shower with towel service The lounge is in Jewel Changi Airport, landside. No need to clear immigration. If you don’t have Visa access, Priority Pass works too for around $32, includes meal and shower. Perfect spot to reset if you’re arriving early
