Ranked for your days
Ground time already subtracts about 3 hours each way for airport check-in, immigration, and the airport–city transfer — so a far-flung red dot really is mostly travel.
Flight times are estimates from great-circle distance — real routes vary with winds, layovers, and schedules. Visa notes are indicative; always confirm with the destination’s embassy or your foreign ministry before booking.
