The method that best avoids creasing for a structured garment like a suit is bundle wrapping: wrapping the jacket and trousers around a soft central core — a rolled sweater or a packing cube — rather than folding flat or rolling the garment on its own. This avoids the sharp, permanent-feeling crease lines a flat fold leaves in tailored fabric.
A dedicated garment bag, either a tri-fold design that packs inside a suitcase or a hanging bag used on arrival, is the other reliable option, and is often simpler than bundle wrapping for a single suit rather than several structured items sharing one case.
Whichever method is used, packing the suit last, on top of softer items, and avoiding placing anything heavy on top of it in transit makes a bigger practical difference than the exact folding technique — pressure over time causes as much creasing as the initial fold.
Check with your airline and read the label before you follow anything here. Lithium battery watt-hour limits, liquids allowances and lock policies differ by carrier and by country, and change over time — the figures published by the airline or security authority you are actually traveling with take precedence over anything written on this site. A power bank or spare battery is carried exactly as its manufacturer and your airline specify, never estimated. We report what is published — a watt-hour rating, a size limit, a lock's official recognition — and this site describes the equipment only: nothing here is a guarantee about what a specific checkpoint will allow on a specific day.
