user: how long is it before you contact someone who's taken my bag by mistake. I've got a lost luggage ref number. Got told today that a similar bag got left so that's who probably has mine. I've got the majority of my clothes in it and want them back asap.
agent: We're sorry, Dan. If we delivered your bag to the carousel and someone else picked it up we're not responsible for contacting them on your behalf. However, if there's been a bag left behind we'll do all we can to get in touch with that customer for them to retrieve it.
user: When I spoke to BA on the phone earlier they said there had been a bag left behind that is similar. They said you can't return theirs until mine has been returned. It's a bit annoying that you can't contact them and enquire if they have mine by mistake. What are my options?
agent: Hi Dan, I can appreciate your frustration. Unfortunately, we're unable to do anything until your bag has been returned, as you already know. You could contact the police and report your bag as stolen, or file a lost bag claim with your travel insurance company.
user: So people can just get off your flights and take whatever baggage they want? great that is!! You literally have to ring up one person and you won't, I'll not be using BA again in a hurry!
agent: Hi Dan. As soon as the passenger who has collected your bag gets back in touch with us, we'll have more information. I'm sorry we're unable to assist further.
user: Thanks Kev how long do I need to leave it before putting a claim in with you or the insurance?
agent: Hi Dan. If another passenger has your bag, you wouldn't be able to make a claim with us. You may be able to claim through your insurance so you may want to contact them.
user: So is there absolutely no possibility that you can contact the person who's bag was left and ask. Obviously I would but you wouldn't be able to give me their details. I've got presents etc in the bag and no money to replace them now, so it's essentially ruined my Christmas.
agent: We wouldn't be able to give you their details for data protection reasons, Dan. We can't guarantee we can do anything, as your bag arrived on the carousel. However, please DM us your baggage ref, email and postal address.

Someone else has taken their bag after a flight and left their own similar case and wants to know when BA will contact the customer, also asks when they can make an insurance claim. Says that BA will not take any steps to contact the person to return the mistaken bag and that the customer could contact the police and report their bag stolen.
