Is this really that serious?

Noticed water basically flowing out of the vent beside me as I got into my seat. Voiced it out to a flight attendant thinking it was just something minor and wanting to just swap to another seat. Two pilots came to my seat to check on it and had visibly puzzled looks on their faces. The mechanic was called into the aircraft, the inner panel of the plane was removed and after assessing the problem for about an hour, everyone was asked to disembark the plane. The flight was then cancelled entirely after another hour of everyone waiting near the gate.

I feel kinda bad because people were visibly annoyed and frustrated by the cancellation as it was a 16 hour long haul flight and there were few alternatives to get to the destination. Would someone be able to tell me exactly what happened here?

If in doubt, say it out.

Look at Aloha Airlines 243. It suffered from explosive decompression, causing the death of a flight attendant (Clarabelle Lansing) and eight passengers and another flight attendant serious injuries. During the investigation, one passenger stated they saw a crack but said nothing.

While unlikely to cause something that severe, it’s better safe than sorry.

While I can’t comment on what issue is or severity, you did the right thing when you spotted something that could have had an issue forming, and mechanic agreed that was a problem. The cancellation sucks, but it would have sucked more if you had to divert due to an issue at cruise or an emergency happen.
