I am much the same. In May on the inaugaural flight to KRK my bag was ripped open. It was the first incident for KRK and they weren't sure what to do. After a lot of faffing I got a PIR. I tweeted to BA and they were nothing but fantastic. A local holiday weekend meant that they couldn't repair/replace it locally but they annotated the booked to say I could take extra hand luggage and I emailed them pictures of the damage. They set up a case, and on my return were very fair in paying for the goods that were damaged and got a replacement case. Brilliant I thought, no compensation sought or offered..

3 weeks later whilst connecting at LHR bags didnt make the connecting flight. Got that dreaded email. Bags were on next flight but this was delayed and would arrive too late to be handed to the courier so would be delivered in next few days. Was only in town 24hrs (needed to check bag in due to liquids) so asked if I could go back to the airport and collect. Duly did this and BA really baulked at reimbursing the cost of taxis to and from the airport to collect this. Got a token amount of AVIOS and eventually the taxis reimbursed. Their glossed up email saying how important they realise baggage is and know how inconvenient it is to be without baggage so they are doing all they can to reuinte me with it totally setting false expectations. In future will simply buy the essentials and in this case a suit or hire of a suit to attend a formal dinner would come to several times the amount of the taxis claimed..
