A smooth airport journey begins before you leave home. Check the spelling of your name on the ticket and compare it with your passport护照. Confirm the airport, terminal航站楼, flight number航班号, and departure time起飞时间. International travelers often arrive three hours early, while two hours may be enough for a domestic flight国内航班. Check whether you need a visa签证, an entry form入境表, or proof of onward travel后续行程证明. Weigh your suitcase行李箱 and review the airline航空公司's baggage allowance行李额度. Keep your passport护照, phone, wallet, medicine, and charging cable in your carry-on随身行李 bag. Download the airline航空公司 app or take a screenshot of the booking confirmation预订确认 in case the internet is unavailable.顺利的机场旅程从出门前开始。核对机票姓名拼写与护照是否一致，并确认机场、航站楼、航班号和起飞时间。国际航班通常提前三小时抵达，国内航班可提前两小时。检查签证、入境表和后续行程证明要求，称好行李并确认额度。护照、手机、钱包、药品和充电线应放在随身行李中。最好下载航空公司应用，或保存预订确认截图以防没有网络。
抵达航站楼 / Arriving At The Terminal
At the airport, follow the signs for departures出发 rather than arrivals到达. Large airports may have several terminals, and moving between them can take time. Look at the flight information display航班信息屏 and search for your flight number航班号. The screen shows the destination目的地, check-in入住/值机 zone, scheduled time计划时间, and current status当前状态. On time准点 means the flight is expected to leave as planned. Delayed延误 means it will leave later, and cancelled取消 means it will not operate. If the terminal航站楼 is wrong, ask, 'How can I get to Terminal航站楼 Two?' You can also say, 'Which counter should I use for flight CA one two three?'到达机场后应跟随出发标志，而不是到达标志。大型机场可能有多个航站楼，换楼需要时间。在航班信息屏上按航班号查找目的地、值机区域、计划时间和当前状态。On time 表示正常，delayed 表示延误，cancelled 表示取消。如果走错航站楼，可以询问如何去二号航站楼，或询问某个航班应使用哪个柜台。
柜台值机 / Checking In
At the check-in counter值机柜台, wait behind the line until an agent calls you forward. Say, 'Hello, I would like to check in for my flight to Singapore.' The agent may ask for your passport护照, booking reference预订编号, or final destination最终目的地. Hand over the document and say, 'Certainly, here you are.' If you checked in online, explain that you only need to drop off a bag. Travelers with connecting flights should ask whether they are checked in all the way through. Ask, 'Will I receive both boarding passes here?' Before leaving, check that your name, destination目的地, and flight number航班号 are correct.在值机柜台排队，工作人员示意后再上前。可以说想办理前往新加坡的航班值机。工作人员可能索要护照、预订编号或询问最终目的地。网上值机后可说明只需要托运行李。有转机时应确认是否已办理全程值机，以及能否在这里拿到两段登机牌。离开前核对姓名、目的地和航班号。
托运行李 / Checking Baggage
Place your suitcase行李箱 on the scale when the agent asks. Checked baggage托运行李 travels in the cargo hold货舱, while carry-on baggage随身行李 stays with you. The agent may say that your bag is over the weight limit重量限制. Ask how much the excess baggage fee超重行李费 is and whether you can move some items to your carry-on随身行李. Tell the agent about fragile易碎的 equipment or special items before the bag is accepted. Never pack power banks充电宝 or spare lithium batteries锂电池 in checked baggage托运行李. Confirm whether the suitcase行李箱 is tagged to your final destination最终目的地. Keep the baggage receipt行李凭证 because its tracking number追踪编号 is useful if the bag is delayed延误 or lost.工作人员要求时把行李箱放到秤上。托运行李进入货舱，随身行李则由自己携带。如果超重，可以询问超重费，或能否把部分物品移到随身包。易碎品和特殊物品要提前说明，充电宝及备用锂电池不可托运。确认行李是否直挂最终目的地，并保存带追踪编号的行李凭证。
选择座位 / Choosing A Seat
The agent may ask whether you prefer a window or an aisle seat靠过道座位. A window seat靠窗座位 offers a view, while an aisle seat靠过道座位 makes it easier to stand up. A middle seat中间座位 is located between two passengers. You can ask, 'Could we have two seats together, please?' An exit-row seat紧急出口排座位 often has extra legroom额外腿部空间 but comes with safety responsibilities. A bulkhead seat has no seat directly in front of it, although storage rules may be different. Some preferred seats require an additional fee额外费用. Check the seat number on your boarding pass登机牌 before you accept it.工作人员可能询问靠窗还是靠过道。靠窗可以看风景，靠过道方便起身，中间座位位于两名乘客之间。同行时可请求相邻座位。紧急出口排通常腿部空间更大，但有安全责任；隔板座前方没有座椅，但储物规则可能不同。部分优选座位需要额外付费，接受前应核对登机牌座位号。
通过安检 / Going Through Security
At security, prepare your boarding pass登机牌 and travel document旅行证件. Put your phone, keys, coins, belt, and jacket into a tray if instructed. Laptops and large electronic devices may need to be removed from the bag. Liquids are usually limited to small containers inside one clear, resealable bag. Tell an officer if you carry medicine, baby food, or medical equipment. Walk through the scanner扫描仪 only when you are invited. If the alarm sounds, remain calm and follow the officer's directions. After screening, collect every item and check the tray carefully before walking away.安检时准备好登机牌和旅行证件。按要求将手机、钥匙、硬币、腰带和外套放入托盘，笔记本电脑等大型电子设备可能需要单独取出。液体通常需装在小容器中，并统一放进透明密封袋。药品、婴儿食品和医疗设备应主动说明。工作人员示意后再通过扫描仪；报警时保持冷静并配合检查。离开前仔细检查托盘，确保拿齐物品。
边检与海关 / Immigration And Customs
For an international flight国际航班, you may pass through passport control边检 after security. The officer may ask where you are going and how long you will stay. Answer briefly and honestly, such as, 'I am visiting for tourism and will stay for seven days.' You may also be asked where you are staying or whether you have a return ticket. Keep the hotel address and itinerary easy to find. On arrival, immigration入境检查 checks your permission to enter the country. Customs海关 is different: it controls goods entering the country. If you carry restricted food受限食品, large amounts of cash, or commercial goods商业货物, declare申报 them as required.国际航班可能在安检后经过边检。工作人员会询问目的地、停留时长、住宿地点或返程机票，应简短如实回答，并把酒店地址和行程放在方便查找的位置。抵达时，移民检查负责入境资格；海关则检查入境物品。携带受限食品、大额现金或商业货物时，应按规定申报。
寻找登机口 / Finding The Gate
After security, check the display again because gate assignments can change. Follow signs showing letters and numbers, and allow enough time for a long walk. Boarding time登机时间 is earlier than departure time起飞时间, so do not confuse the two. If you are unsure, ask, 'Is gate B twelve far from here?' At the gate, confirm that the destination目的地 and flight number航班号 on the screen match your boarding pass登机牌. Listen for announcements about a gate change登机口变更, delay, or final call最后召集. Charge your phone and use the restroom before boarding begins. Stay close enough to hear announcements, but do not block the boarding lane.安检后再次查看屏幕，因为登机口可能改变。跟随字母和数字标志，并为较远的步行距离预留时间。登机时间早于起飞时间，不要混淆。到达登机口后，确认屏幕上的目的地和航班号与登机牌一致。留意登机口变更、延误和最后召集广播。登机前可充电和使用洗手间，并避免堵住登机通道。
登机 / Boarding The Plane
Airlines usually board passengers by group, zone, or row. Wait until your group is called instead of joining the line too early. Have your boarding pass登机牌 and passport护照 ready for inspection. The agent may scan the code and say, 'You may board now.' Walk through the jet bridge登机廊桥 or follow directions to a shuttle bus. On the aircraft, find the row first and then check the seat letter. Put a small personal item under the seat and a larger carry-on随身行李 in the overhead bin行李架. Sit down, fasten your seat belt, and keep the aisle clear.航空公司通常按组别、区域或排号登机，应等自己的组别被叫到再排队。提前准备登机牌和护照供检查。通过扫描后，沿廊桥或按指示乘摆渡车前往飞机。进入机舱后先找排号，再找座位字母。小件个人物品放座位下，较大的随身行李放行李架。坐好后系安全带并保持通道畅通。
转机 / Making A Connection
A connecting flight转机航班 requires you to change planes before reaching the final destination最终目的地. Follow signs for flight connections连接航班 or transfers, not baggage claim行李提取. Check the next flight's gate and boarding time登机时间 as soon as possible. Depending on the airport, you may need another security check or passport护照 inspection. Ask, 'Is my baggage checked through to Paris?' If the first flight is late, tell airline航空公司 staff that you have a short connection. They may direct you to a faster route or rebook改签 the next flight. Never leave the secure area安检区域 unless signs or staff tell you to do so.转机是到达最终目的地前更换飞机。应跟随连接航班或中转标志，而不是行李提取标志，并尽快查看下一航班的登机口和时间。部分机场需要再次安检或查验护照。应确认行李是否直挂。如果前一航班延误且转机时间紧，及时告知航空公司，工作人员可能提供快捷路线或改签。除非有明确指示，不要离开安检区域。
航班延误或取消 / Delays And Cancellations
When a flight is delayed延误, first check the app and departure screen出发信息屏 for updates. Ask the agent for the new estimated departure time预计起飞时间. If the delay threatens a connection, request help before the next flight closes. When a flight is cancelled取消, ask whether you will be rebooked automatically. You can say, 'What is the earliest available flight to my destination目的地?' Also ask about meal vouchers餐券, hotel accommodation酒店住宿, and checked baggage托运行李 when appropriate. Keep receipts if the airline航空公司 tells you to arrange essential expenses yourself. Remain polite, write down important details, and confirm the new booking before leaving the desk.航班延误时先查看应用和出发屏幕，并询问新的预计起飞时间。如果影响转机，应在下一航班关闭前求助。航班取消时，询问是否会自动改签，以及最早的替代航班。根据情况询问餐券、酒店住宿和托运行李安排。若航空公司要求自行支付必要费用，应保留收据。保持礼貌，记下关键信息，并在离开柜台前确认新预订。
到达与行李提取 / Arrival And Baggage Claim
After landing, follow signs for arrivals到达, immigration入境检查, and baggage claim行李提取. Look for your flight number航班号 on the carousel行李转盘 display. Suitcases from one flight may arrive on more than one belt. Compare the baggage tag before taking a bag that looks like yours. If your suitcase行李箱 does not arrive, go to the baggage service desk before leaving the hall. Show the baggage receipt行李凭证 and describe the color, size, and brand of the suitcase行李箱. Ask how to track the report and when delivery is expected. After collecting everything, follow the correct customs channel海关通道 and then look for ground transportation地面交通 signs.落地后跟随到达、入境检查和行李提取标志。在转盘屏幕上查找航班号，同一航班的行李有时会出现在多个转盘。拿走相似行李前核对行李牌。如果行李未到，应在离开大厅前前往行李服务柜台，出示凭证并描述颜色、尺寸和品牌，询问如何追踪以及预计送达时间。取齐行李后通过正确的海关通道，再寻找地面交通。
