Back in July we missed our flight to my best friend's wedding due to utter chaos at the BA check-in desk. We were there 3h before the flight and only got to the front of the queue 30mn before our flight despite me trying to get help from BA colleagues to get checked in sooner. We had checked in online but had to stick to a specific desk to check-in at Heathrow due to having a buggy with us. Once we got to the front of the queue we had to wait even further as a BA colleague supporting another family whose flight was later than ours came and commandeered the check-in desk stating she'd be really quick but that query ended up being bigger than shed thought which ultimately led us to miss our flight. Despite our bags being checked in and our boarding passes printed, by the time we go to security a matter of minutes later they denied us entry. Our bags eventually were delivered back home 14 days later and one had been broken into (it had a built in lock) and items were missing along with wedding presents/card being ripped open and damaged. Whilst our bags were missing we were advised over the phone by 2 BA colleagues we could claim for essential items which we did as we had some items for our baby in the cases that we needed, the claim was less than £100.
Has anyone had success in a similar situation to claim compensation as BA currently are declining anything including our expenses claim?
