e-Arrival Card Submitted with Incorrect Flight Number

I traveled from Melbourne a few weeks ago and accidentally entered the wrong airline code on my form. Everything else, including my passport number and travel date, was accurate.

Since I couldn't edit the application, I kept copies of my boarding pass and booking confirmation with me during travel. Fortunately, nothing was questioned during my trip.

Based on my experience, it's usually better not to submit multiple applications unless you're certain the original one should be replaced. Requirements and procedures can change, so I'd verify the current guidance before making any changes.

My experience was slightly different. I was flying from London, and my connecting flight changed after I had already submitted my e-Arrival Card.

I contacted the support information listed on the official portal to ask whether I needed to submit a new application. They advised me based on my specific situation, so I followed their instructions rather than guessing.

If your departure is still several days away, it may be worth reaching out through the official support channels instead of creating a duplicate submission.

I had a similar situation while traveling from New Jersey earlier this year. I entered the wrong flight number because my airline changed my booking a few days before departure.

I couldn't find an edit option after submitting the e-Arrival Card either. Since all my personal information and passport details were correct, I kept a copy of my updated flight itinerary with me. I didn't run into any issues during my arrival, but that's just my experience and yours could be different.

If your flight has actually changed, I'd still check the latest guidance on the official portal to see whether an update is recommended.
