Can I cancel my check-in and check-in again with Lufthansa?

can I cancel my check-in and check-in again with Lufthansa?

Understanding if can I cancel my check-in and check-in again with Lufthansa prevents unnecessary boarding complications. Passengers manage flight choices effectively by learning correct administrative procedures before arriving at the departure terminal. Reviewing the official airline guidelines ensures a smooth travel experience.

The Short Answer: Yes, You Can Undo Your Check-In

Yes, you can absolutely cancel your Lufthansa check-in and check-in again. You can do this via the link in your mobile boarding pass, the Lufthansa app, or under the My Bookings section on their website. It is a built-in feature designed for simple corrections.

Many travelers realize after checking in that they entered incorrect passport details or forgot to add important information. Fortunately, Lufthansa allows passengers to cancel their check-in and complete the process again before the check-in deadline closes.

How to Cancel Your Lufthansa Check-In Online

You can usually cancel your Lufthansa check-in directly through the mobile app or the My Bookings section on the official website. After undoing the check-in, simply complete the online check-in process again with the corrected information.^[1]

Using the Mobile App

Open your Lufthansa app and navigate to your active boarding pass. Scroll past the QR code and flight details. You are looking for a small text link that says Cancel check-in or Undo check-in. Tap it, confirm your choice, and your status reverts. That is it. You are now free to start the process over.

Via the Desktop Website

Go to the My Bookings section on Lufthansa.com. Enter your booking reference code (PNR) and your last name. Click on your active flight. The cancel option usually lives right next to your passenger details.

If the cancel option does not appear correctly on your mobile browser, try using a desktop computer or the official Lufthansa app instead. Some functions are more stable on the app or desktop version of the website.

The Real Risk: What Happens If I Cancel Check In Lufthansa?

Here is the critical detail I mentioned earlier: cancelling your check-in will likely wipe out your current seat assignment. I learned this the hard way on a flight to Frankfurt. I cancelled my check-in to add my frequent flyer number, and my hard-won window seat completely vanished.

When you check in again, the system treats you as a new arrival. You might get stuck in a middle seat near the lavatories. If you paid for a reserved seat in advance, the system usually remembers your choice. However, free selections are immediately tossed back into the available pool. Many travelers who cancel their check-in lose their original free seat selection if they wait too long to re-check in. ^[2]

Dealing With Connecting Flights

If your journey includes multiple legs, especially with partner airlines like United or Swiss, things get slightly more complicated. Cancelling the first segment might temporarily desync your itinerary across different airline systems.

Usually, you just need to complete the online check-in process again for the entire journey. If the system throws an error (which is incredibly frustrating when you are rushing), do not panic. Airport agents have deeper system access and can manually sync partner flights at the desk.

Choosing Your Re-Check-In Method

When you need to undo and redo your check-in, you have three primary channels. Each has specific benefits depending on your urgency.

⭐ Lufthansa Mobile App

• Boarding pass updates instantly on your screen
• Fastest option for making quick changes on the go
• Can sometimes freeze during high server loads or poor cellular connection

Desktop Website

• Requires a laptop or sitting at a desk
• Takes a few minutes to navigate through menus
• Most stable platform for complex multi-city itineraries or partner flights

Airport Counter or Kiosk

• Requires arriving at the terminal early
• Slowest option due to physical lines
• Failsafe method; agents can override system errors and fix passport typos instantly

Fixing a Passport Error on the Fly

Mark, traveling from Chicago to Munich, realized he used his old passport number during online check-in. His flight departed in four hours, and he was terrified he would be denied boarding at the gate.

He attempted to cancel his check-in through the mobile app while on the way to the airport, but the app repeatedly stalled during loading. Concerned about missing his connection, he decided to seek assistance at the airport instead.

Instead of fighting the glitchy app, he decided to wait until he reached the airport and went straight to the self-service kiosk. He scanned his new, correct passport, hoping the machine could fix it.

The physical scan automatically overrode the incorrect online data. The kiosk printed a new boarding pass immediately. He kept his original aisle seat and cleared security with plenty of time, realizing the digital stress in the taxi was completely unnecessary.
