If you buy a connecting ticket, you can go through the exit formalities from the United States in Chicago. When you arrive in Washington DC, you won't need to take out your luggage, so you can take the United Airlines flight directly to the boarding gate. If you buy air tickets separately, the 5-minute connecting flight time is definitely not enough for you. You must take out your luggage before you check in. Maybe the check-in counter is closed at this time. Or you can advance the flight time from Chicago to Washington DC by two hours. I suggest you consult the travel agency that bought the air ticket, or consult CO and UA airlines.

CO and UA have merged into one company. Your ticket should be a joint ticket, otherwise the travel agency can I can't sell it to you. T guarantee your connecting flight time, but they will be responsible for the cost of your flight delay.

I suggest you look at other websites such as Expedia, Priceline and so on.

6. Raiders for returning home from Chicago, USA

One of the precautions for traveling in the United States: preparation 1. Most American hotels do not provide toothbrushes, toothpaste, slippers and other related toiletries. Please prepare yourself. Please bring appropriate clothes, especially comfortable, light and casual clothes. Please take a coat in summer in case it gets cold at night. It is cold in winter in the eastern United States. Please keep warm. In addition, because the sunshine in the United States is very strong, you can prepare umbrellas, sun hats, sunglasses and sunscreen lotion, and pay attention to sun protection. As the US Customs has strict restrictions and regulations on the import of agricultural products, please pay attention when preparing food. Do not bring fresh or preserved animal and plant products such as meat, eggs, vegetables and fruits into the country. If you bring any food, no matter what kind, you must declare it at the customs. If you bring any food, it is recommended to tell the tour leader before entering the customs for reference. 4. If you have first-aid medicines for travel, please try to bring the packaged medicines, preferably with English names, and store them in a unified way. It is suggested that you inform the tour leader before entering the customs for your reference. Notes on American Travel 2: Entry and Exit 1. Entry notice: According to the immigration law of the United States, all people who enter the United States from land ports, airport ports or seaports are subject to inspection. If you fly to the United States, the flight attendant will send you an I-94 form, that is, the arrival/departure record, which records the personal information of the immigrant and his address in the United States. There are four main inspection items at the entry port in the United States: 1. Public health; 2. Immigration status; 3. Customs inspection; 4. Agricultural inspection. These four inspections can be conducted by one official or several officials. On the way to the United States, flight attendants will distribute the I-94 form to passengers for them to fill out. Passengers fill in their basic personal information and address in the United States on this form. At the port of entry, the immigration officer will check the documents and valid visas held by the immigrants and the reasons for going to the United States, and decide whether to allow the inspected people to enter the country and how long they can stay in the United States. If you are allowed to enter the country, the immigration officer will stamp the I-94 form of the entrant, and indicate the date of entry, visa status and length of stay in the United States. It should be noted that holding a valid American visa does not guarantee entry, and immigration officials at American ports finally decide whether to allow you to enter the country. Form I-94 is the proof of legal entry into the United States, which has been reviewed and approved by the port immigration officer. Take good care of it. If it is lost or damaged, it should be reported to the nearby immigrants in time and reissued. Form I-94 should be returned to the port immigration officer when leaving the United States. Passports must be valid for more than six months beyond the scheduled stay in the United States. 2. Safety regulations In order to improve the safety of passengers, the United States has restrictions on carrying liquids, sprays and hairspray on inbound and outbound flights. These regulations are necessary to protect you from the threat of liquid explosion. The liquid, spray or hair gel container in hand luggage must be 1 ml or less. All containers must be sealed in a transparent plastic bag with a capacity of one liter, and each person is limited to one plastic bag. Passengers are allowed to use automatic sealing bags with a capacity of 1 liter or less. Prescription drugs can still pass the security check. Passengers can carry baby products and prescription drugs on the plane, but you may need to show proof of demand. When you arrive at the security checkpoint, you must hand over any liquids, sprays and hairspray you still carry with you, including duty-free goods. The new regulations will also increase random body searches during security inspection. Please prepare plastic bags before check-in so as to have time to put the oversized containers into the check-in luggage. 3. Before check-in, arrange the liquid, spray and hair gel to take on the plane according to the steps. If possible, please make preparations before going to the airport. The liquid, spray and hair gel contained in hand luggage must be packed in containers with a capacity of 1ml or less (with a weight of about 1g). Containers exceeding 1ml should be packed in checked bags or not taken away. Half-full containers with a capacity of more than 1ml cannot be carried. Please keep the container to be put at hand

If it is not well sealed, some articles will be removed, and only one plastic bag is allowed per person. Please put the plastic bag where it is easy to get in your hand luggage. Plastic bags should be handed over to security personnel for inspection. At the security checkpoint, you should show the plastic bag to the security personnel alone. Security personnel may ask for proof that you need to take medicine aboard, such as comparing the name on the prescription with your boarding pass. Please take off your coat. You may have to be searched. These regulations also apply to passengers transiting through American international airports. Many airports can buy duty-free goods, drinks and other items as long as they enter the safe area through security checkpoints. These items can be taken with you.
