This hack is all about timing and avoiding the crush. Around 20 minutes before landing, when the pilot typically announces the descent and the seatbelt sign illuminates, seize the chance to visit the aeroplane lavatory. Most planes have a slight grace period (perhaps 15 minutes) where you are not strictly required to be seated, allowing you to use the facilities before the final approach.
Utilising this short window prevents the inevitable post-landing rush, where everyone simultaneously tries to use the terminal restrooms. Having already relieved yourself, you can walk straight off the plane, feeling refreshed and ready to tackle the queues for immigration or baggage claim without that uncomfortable delay.
