Empty plane seats next to you

There are few pleasures in modern travel as pure, as unadulterated, as the discovery that the seat beside you on a plane is gloriously, magnificently empty. It is the aviation equivalent of stumbling upon buried treasure - except the treasure is legroom, elbow room, and the intoxicating freedom to sprawl like a monarch surveying their airborne dominion.

Suddenly, the cramped row transforms into a private lounge. If more than one seat next to you is empty, you can go crazy with joy - stretch your legs diagonally, lift both armrests without guilt, and even lay across the three seats to travel 'first class'. The middle seat, a dreaded purgatory of sighs, becomes a sacred buffer zone, a silent guardian of personal space.

The bliss is not just physical but psychological. You are no longer a sardine in a pressurised tin can - you are the chosen one in a universe in which god does play dice. Every bump of turbulence feels less menacing when you can recline without apologising to a stranger's knees. Every snack packet tastes gourmet when consumed with the smug knowledge that you, and only you, have space - and not just in your stomach.
