10 Secrets Kept by Airline Check-in Staff

Here are 10 secrets airline check-in staff won’t tell passengers; but knowing them can help you navigate your travels more smoothly!

1. You Can Sometimes Check in More Than Your Allowance

If a flight isn't full, check-in staff might let you check extra baggage for free—especially if you’re polite and ask nicely.

2. They Can Change Your Seat—Even After Check-in

If you’re unhappy with your seat, check-in agents have the power to switch it, even for a better one. It’s not always guaranteed, but being friendly increases your chances.

3. Weight Limits Are Flexible (to a Point)

Most airlines allow a little leeway on baggage weight (usually 1–2 kg) before charging fees. If your bag is slightly overweight, shifting items to your carry-on might help you avoid the charge.

4. Your Passport Can Get You Turned Away—Even If Valid

Some countries require at least six months’ validity on your passport. Check-in staff will refuse boarding if you don’t meet the entry requirements, even if your passport is technically still valid.

5. Being Late? They Can Hold the Flight (But Rarely Do)

If a flight is slightly delayed, staff can request to hold the plane for a few more minutes if many passengers are missing—but they rarely do unless it’s in the airline’s best interest.

6. They Know When Flights Are Overbooked—Before You Do

Airlines overbook flights intentionally because they expect no-shows. Check-in staff already know if you’re at risk of getting bumped but won’t say anything unless necessary.

7. They Have the Power to Waive Fees

Fees for excess baggage, seat changes, or name corrections aren’t always set in stone. Being polite and understanding can sometimes get you a free pass.

8. Your Checked Bag Might Not Make It

Even if your bag is tagged correctly, tight connections or last-minute check-ins increase the chances of it being left behind. Always pack essentials in your carry-on.

9. They Can Upgrade You—But Rarely Do

Free upgrades are rare, but check-in staff have the power to bump passengers to business class when flights are oversold in economy. Loyalty status and being well-dressed increase your chances.

10. They Know Who’s on the ‘Do Not Fly’ List

Check-in agents have access to security watchlists and know when someone is flagged for additional screening—or isn’t allowed to board at all.
