When leaving the country by plane, you must first check in your luggage, exchange for a boarding pass, and then go through departure and security checks before entering the waiting area. Various consumer facilities are set up in the general waiting area, including duty-free shops, restaurants, transit hotels, luggage storage, Singapore Changi Airport and a butterfly park. Some people need to transfer at the airport and can only spend a few hours or even ten hours there.

After arriving at the airport, you can also shop first and then collect your luggage for departure. Everything depends on your time arrangement and customs inspection requirements. For example, if you arrive at Singapore Changi Airport at 9 p.m., and you want to catch the subway to your hotel in the city, you won’t have time to go shopping. For example, if you arrive at Beijing Airport and want to buy two bottles of wine, but you have already bought enough at Singapore Changi Airport, then you can no longer buy wine at the duty-free shop at Beijing Airport. Even if you don’t have any of these restrictions, consider the hassle that could arise if your checked bag is left unclaimed if you take too long to shop.

In short, enough is enough.
