I have a booking made by my company TA, however, when I try to access this booking via the App or on BA.com am getting the message "Error - Access to this booking has now been prohibited due to too many unsuccessful attempts. Please check your travel details are correct and retry in 24 hours". The first time this happened with this booking was shortly after it had been made - that time I called the GGL, the guy there went into the booking, couldn't see any issues, but for whatever reason I could then access the booking again straight after that call. Now it has happened again. I'm within 24 hours of travel, but it won't let me check-in online. I called the GGL again, they checked the booking and again said they cannot see any issues with it. But I still can't access it or check-in, so they said I would just need to check-in at the airport.

I have only accessed this booking via the App or BA.com, so cannot see how I could have locked it out. So unless someone else has been trying to access my booking I'm not sure why this has been happening. A quick search only came up with a couple of references to this error from a few years ago. Has anyone else experienced this recently? Should I be concerned? (the GGL guy was confident there would be no issues about checking me in at the airport).

I'm just a bit confused as to why there isn't some flag on the booking that the agents can see when they go into the booking. Surely if it is a booking security feature there should be something obvious to the agents when they look at it?
