Is it just me that has been getting this error on BA.com for the last few days?

That seems to be a new one. Every other error has been reported here. The site has actually been behaving for me recently.

Have you tried some of the tips on this thread?

Same error yesterday and today on two accounts, also with different browsers. App is fine.

Had this on and off over the last week or so, both app and website. Going straight in via MMB didn’t help.

Also having this – which is annoying as they’ve only just unlocked my account after locking me out “to protect my security”.

I have had this on and off since Friday.

Right, I think I’ve managed to sort it, as it was happening both on desktop (safari), mobile browser (safari) and iPhone.

You need to delete the website data & cookies on the browser just for britishairways.com, and on the app because it has a built in browser it uses for most tasks you have to delete the app, and then re-install.

After doing both of these things, it appears to be consistently working for me.

I spoke too soon… BA simply tweeting out to multiple folks that they ‘can’t replicate it’ which isn’t useful at all.

Posted this on another post but I had the same problem and found a fix:

Occasionally your internet provider is blocked by BA’s firewall. It could be by chance there’s a lot of people from your ISP contacting BA. BA’s server used for login is different from the webpages, this is why you can go on the homepage fine until you try to login or reset password. After a time period passes it fixes itself.

This also explains why BA can’t replicate it.

The quick fix is to hotspot onto your mobile data to login, unless you have another wifi you can use. Once you’ve logged in you can use your wifi again to browse the exec account pages.

Same issue tethering to mobile data too, on multiple devices too.

This particular error flags up just going to the homepage, no opportunity to login.

I now suspect a change to BA’s web server may have throttled a vast range of IP addresses at an xxx.xxx.>>>.>>> level, and is blocking access after a certain threshold. Part of the problem of BA’s walled garden of support is no one from the Social Team will either understand this, or communicate it up the chain.
