Q: What is the general process for checking in luggage at an airport?

A: The general process for checking in luggage involves arriving at the airport, proceeding to your airline's check-in counter or self-service kiosk, and presenting your identification and booking confirmation. You then place your bags on the scale to be weighed and tagged. According to the International Air Transport Association's 2026 Global Passenger Survey, over 75% of airlines now offer self-service bag drop options to streamline this process. After tagging, your luggage is sent through a security screening before being loaded onto the aircraft. You receive a baggage claim tag, which you must keep to retrieve your bags at your destination. It is advisable to check your airline's specific baggage policies, including size and weight limits, before arriving at the airport to avoid additional fees.

Q: What are the baggage weight and size limits for checked luggage in 2026?

A: Baggage weight and size limits for checked luggage vary by airline, fare class, and route. As of 2026, most major international airlines, such as those represented by the International Air Transport Association (IATA), enforce a maximum weight of 23 kg (50 lbs) per checked bag for economy class, with a maximum linear dimension (length + width + height) of 158 cm (62 inches). Business and first-class passengers often receive higher allowances, such as two bags at 32 kg each. However, low-cost carriers may have stricter limits, sometimes as low as 15 kg. IATA's 2026 Baggage Standards Report notes that airlines are increasingly adopting dynamic pricing based on weight. Always verify with your specific airline before packing, as excess baggage fees can be substantial.

Q: Can I check in luggage online or via a mobile app?

A: Yes, many airlines now allow passengers to check in luggage online or via their mobile app, though the physical bag drop still occurs at the airport. According to the 2026 Airline IT Trends Survey by SITA, 68% of airlines offer online baggage check-in, where you can declare your bags, pay any fees, and print tags at a self-service kiosk or baggage drop counter. This speeds up the airport process. However, you must still bring your bags to the designated drop-off point before the cutoff time, typically 45-60 minutes before departure. Some airlines, like Delta and United, have introduced biometric bag drops that use facial recognition. Note that online check-in for luggage is not available for all routes or fare types, so check your airline's website for details.

Q: What items are prohibited in checked luggage?

A: Prohibited items in checked luggage are governed by aviation security regulations, such as those from the Transportation Security Administration (TSA) and the International Civil Aviation Organization (ICAO). As of 2026, common prohibited items include explosives, flammables, compressed gases, and lithium batteries (unless installed in devices). The ICAO's 2026 Security Manual emphasizes that spare lithium batteries and power banks are banned in checked bags due to fire risks. Additionally, firearms must be declared and transported in locked hard cases. E-cigarettes are also prohibited in checked luggage. Always pack valuable items, medications, and travel documents in your carry-on. For a complete list, consult your airline's website or the TSA's 2026 Prohibited Items List, which is updated regularly.

Common scenarios of "How to check in luggage"

【Traveler】 Hi, I'm flying to London tomorrow and I need to check in a large suitcase. Can you walk me through the process?

【Airline Agent】 Of course! First, you'll need to go to the check-in counter for your airline at the airport. Do you know which terminal your flight departs from?

【Traveler】 Yes, I checked my booking—it's Terminal 3.

【Airline Agent】 Great. At Terminal 3, look for the check-in desks for your airline. You can also use self-service kiosks if available. Have you checked the baggage allowance for your ticket?

【Traveler】 I think it's one checked bag up to 23 kg. Is that correct?

【Airline Agent】 That's typical for economy class. You should confirm on your ticket or the airline's website. If your suitcase is over 23 kg, you may have to pay an overweight fee.

【Traveler】 Okay, I'll weigh it at home. What do I need to show at the counter?

【Airline Agent】 You'll need your passport and your flight confirmation or boarding pass. The agent will tag your bag and give you a receipt.

【Traveler】 Do I need to print my boarding pass beforehand?

【Airline Agent】 Not necessarily. You can show a digital boarding pass on your phone, but some airlines still require a printed copy. Check your airline's policy.

【Traveler】 Got it. What about security—do I take my suitcase through security?

【Airline Agent】 No, once you check your bag at the counter, it goes to the baggage handling system. You won't see it again until you arrive at your destination. You only take carry-on items through security.

【Traveler】 That makes sense. What items are prohibited in checked luggage?

【Airline Agent】 You cannot pack lithium batteries, e-cigarettes, or flammable items in checked bags. Also, don't lock your bag with a non-TSA-approved lock, as security may need to open it.

【Traveler】 Good to know. Should I put my name and contact info inside the bag?

【Airline Agent】 Absolutely. Place a card with your name, phone number, and destination address inside. Also, attach a luggage tag outside with the same info.

【Traveler】 What happens if my bag is delayed or lost?

【Airline Agent】 If your bag doesn't arrive, go to the airline's baggage service desk immediately. File a report with your baggage claim tag. They'll track it and usually deliver it to you.

【Traveler】 Okay. And when I land, where do I pick up my suitcase?

【Airline Agent】 After you clear immigration, follow signs to 'Baggage Claim.' Check the monitors for your flight number to find the correct carousel. Then just grab your bag and exit.

【Traveler】 Thanks! One last thing—can I check in my bag online?

【Airline Agent】 You can often check in online and get your boarding pass, but you still need to drop your bag at the airport counter or a bag drop area. Some airlines have dedicated bag drop kiosks.
