Wow. That is bloody amazing! Another huge ^ to the staff at ORD who are often cited on here as being excellent.

Were these paid or award tickets out of interest?

So much negativity and so many complaints here usually, this is a really, really nice positive story to see. Please, if you can spare the time they inevitably saved you , I urge you to write in to BA and make it formal - this deserves to be on the staff files as big praise (especially if you can recall their names).
