The biggest delays at check-in usually come down to passengers who are just not prepared. Missing documents, overweight bags it's just a recipe for disaster, especially during peak hours. I've seen whole lines come to a standstill because someone needs to repack a bag at the counter. And that one little delay can end up costing people their flights and stressing out the staff. Simple solutions work best: just get your documents in order and weigh your luggage before you leave home. The smoother your first interaction with the airline, the faster the whole line will move.
One of the biggest things that slows down the check-in line is passengers arriving without their documents ready. This includes passports, visas, or even basic ID for domestic flights. When people start searching through bags or phones at the counter, it holds up everyone behind them. I always recommend having documents out and open before reaching the desk." "Another common issue is baggage problems. Oversized, overweight, or incorrectly packed bags cause delays because they need to be repacked, paid for, or sent for special handling. A lot of passengers are surprised by weight limits. Using a small luggage scale at home can prevent this, and packing heavier items in carry-on when allowed also helps." "Traveling as a group can also slow things down if one person holds all the documents or bags and they aren't organized. Each traveler having their own documents ready makes a big difference." "One memorable delay I've seen was when a passenger arrived for an international flight without checking visa requirements. The discussion at the counter took more than 15 minutes and stopped the entire line. It was stressful for everyone involved. A quick check of entry rules before leaving home would have avoided that situation." "My best advice is simple: arrive early, check baggage rules ahead of time, and keep documents and boarding information easy to reach. Small steps like using travel organizers or checking in online can save a lot of time and reduce stress for both passengers and staff."
I'll never forget the time one of our bestselling authors missed a major book launch keynote after spending nearly 90 minutes stuck in the check in line at O'Hare. Watching that unfold was my wake up call about how easily small hiccups at the airport can snowball into real problems. From what I've seen managing travel for speakers and executives, most check in delays aren't caused by the agents they're caused by passengers arriving unprepared. People show up without checking in online, realize at the counter that their bag is overweight, or need special accommodations they didn't arrange in advance. Each situation adds a few minutes, and those minutes stack up fast. Our biggest fix has been preparation. We tell travelers to check in online the moment it opens usually 24 hours before departure and to review baggage rules before leaving home, not at the counter. A simple luggage scale and having your ID and boarding pass ready on your phone can save everyone time. One thing people underestimate is the human side of it. I always remind our speakers to be patient and kind with ticket agents. I've seen agents go out of their way to help polite passengers reroute flights or fix issues, and I've seen them stick strictly to policy when someone arrives frustrated. A little empathy can be the difference between a quick resolution and a long delay for you and everyone behind you in line.
I'm not an airline employee, but my team and I also escort thousands of travelers through airports and spend a lot of time with check-in agents — so I see what slows lines. The biggest issue tends to be documents: folks show up with passports stowed in bags, a name that doesn't match the one on their ticket, absent visas or no means to pay bag fees. Continue keeping your passport and visas in one place, but make more basic offline versions on your phone so you can whip them out quickly. Next, bags: Overweight or oddly-shaped luggage is what causes people to unpack at the counter. Weigh bags at home with a small digital scale, and pack an ultralight, collapsible duffel so you can easily layer on extra weight if necessary. Tip 8: Declare special items, such as sports equipment (including skis), strollers, and batteries, immediately. Remember that power banks and loose lithium batteries must travel in the cabin baggage, not as checked luggage. Check in on the airline app and add traveler information, prepay for bags and screenshot your boarding pass so you can use bag drop.
