Got an email from British Airways that the flight I was taking was changed to have a 20 min connection and the standard, call or accept. I called the number on the email after confirming that the email was in fact from BA by checking the "to" line. Was on hold for a min, then it seemed like the music changed and then someone picked up. I got a weird feeling during the conversation as they just did not seem that helpful and wanted to to have me pay them, so I hung up. Went online and looked up the phone number on the BA site and called from there and got someone else who was very professional. Thankfully I did not fall for "whatever" that other line was. Not sure if AI is helping scammers find flights that are changed and then setting up fake emails or what.
Just a warning to be sure you are on with the airline...I was, and then I think I wasn't. And yes, as BA records calls, and I mentioned it, they are aware of the issue that I hade.
Edit to add it was an actual change, but the phone number was perhaps "intercepted", or rerouted.
