The AI answer we saw
Most airlines accept carry-on bags up to 22x14x9 inches (56x36x23 cm), including wheels and handles. A 20-inch carry-on suitcase typically fits within these dimensions and works on the majority of domestic and international carriers. Budget and regional airlines (like Spirit or Ryanair) may have stricter limits around 18x14x8 inches, so always verify the specific airline's policy before traveling. A 20-inch spinner is the safest universal choice for overhead bin compatibility.
