Asian airlines generally provide two free checked bags (23kg each).

If you want to sit comfortably, you don’t necessarily have to upgrade. The following are practical seat selection suggestions:

Check in online in advance
United, Delta, and American Airlines all provide online seat selection 24 hours in advance. You can grab a good seat as soon as possible.

Holding a Chinese passport: You must have a valid US visa (common B1/B2 tourist visa).
Visa review has become stricter in recent years. It is recommended to apply at least 2-3 months in advance.
Transit issues in non-direct countries
If you plan to transit through Canada, you must apply for a Canadian visa or eTA; you need a Schengen visa when transiting through some EU countries, so don’t ignore it.
7. Food and flight comfort: Don’t count on airplane meals

You can bring vacuum-packed dry food, nuts, biscuits, and dried fruits.
Buy water at the airport before boarding (purchase after passing security).

Seoul Incheon: Asiana/Korean Airlines have complete transit facilities and many Chinese services.
San Francisco, Chicago, Los Angeles: classic gateway airports for entering the United States, you need to pick up your luggage and then check it in.
Avoid transit airports:
New York JFK: chaos, long queues, and separate terminals.
Chicago ORD (frequent bad weather): prone to delays in winter.
Dallas DFW: American Airlines’ main base, but the terminal spans a large area, so you need to reserve at least 2 hours for transfer time.
10. Network and payment method preparation after entry
Mobile phone and SIM card
It is recommended to buy eSIM or short-term cards from T-Mobile or AT&T.
There are generally no convenience stores selling SIM cards at US airports, so it is recommended to buy online in advance.
Payment method

WeChat and Alipay are available in some Chinese stores, but they cannot be relied on.
Houston is a city full of opportunities and cultural charm, but the journey to it is full of “unspoken rules” and precautions. From airline selection to baggage check-in, from seat selection to customs clearance, every step may affect your travel experience.
These 10 things may seem trivial, but they are the key to whether you can easily fly to Houston and embark on a smooth journey. I wish you a happy flight and a smooth journey!
