AIBU to expect payment when my sister's boyfriend used my concert ticket?

No tough luck, he wasn't even bothered about going. You could of gotten organised and sold the ticket, even at last minute on a ticket resell website.

Did you at any point make it clear that you wanted payment for the ticket and if no one from your family wanted to buy it, you were wanting to sell it to someone else?

If you did, and they pissed you about until it was too late to do that, then I think a token amount since it was used, would be fair.

If you didn't though, then no. It all boils down to communication really!

So what did you think happened to the ticket?
Presumably you thought it hadn't been used and you said yourself you had no time to sell it.
I don't see what the difference is, the ticket would have been wasted anyway and you wouldn't have got any money for it.

If you could have got a refund on your ticket they should give you some money.

If the ticket was non refundable you would have lost the money anyway. It would have been nice of them to give you a few quid/box of chocs as a thank you though.

Wow typing is off the charts bad today - you get the drift

OP didn't get any enjoyment as she double booker herself in the first place and then took no personal responsibility to sell the ticket.

The ticket would of went to waste, it was worthless by the time the BF stepped in. Its petty.

Sorryeamy to say O offered to pay!

i've gone to see shows in London a couple of times when friends have booked but been unable to attend. I've offered to attend but they said no as it was their bad that they couldn't go

Nah. A month out you should have said to dsis 1 " I'm putting my ticket on stubhub tomorrow. Let me know tonight if you want it"
If boyf has gone along to see ( wild guess Harry Styles or someone ) cos it's free, it ain't on him

You sound pretty grabby and petty to be honest.
If you were going to sell it and they asked for it early on then fair enough you should get the money, but it was going to waste!

I'm guessing they didn't tell you because they knew you would be unreasonable about it!

Why would you have asked him to pay when he didn’t really want to go, and you were going to lose your money anyway?!
That’s just tight!

No I would not have expected payment, not even a token amount. I would however expected your sister 2 to give you a text to say he is using it just to be polite.

However I am at a lost why you left your sister 1 mess you about regarding the ticket. Surely you could have looked up on ticketmaster etc whether you niece would be able to attend or not and then have plenty of time to sell the ticket.

Did you want payment for the ticket, even if your niece had used it? Of did you only want payment because your sister's boyfriend used it instead? If you didn't ask for payment, then you can't really complain when no money was given. Having said that, family or not, my first question would have been 'do you want any money for the ticket'. I wouldn't have assumed the ticket was a freebie!

Eh? If neither could go then they could have sold both tickets, obviously

Sorry OP but this sounds like a situation all of your own making… from the post (I could be wrong), it sounds like your sister is the one who has had the responsibility of organising/booking etc? Your part in this has been to double book an event, and then be very passive in terms of selling on the ticket. If financial compensation was a priority for you, you really should have got on and sold the ticket straight away, not 2 days before the event. I do agree it would have been courteous/ nice for sister to check about using the ticket to prevent it going to waste, but I think it’s a dog-in-the-manger response to say the boyfriend can’t go unless he pays- you’d really rather see it go to complete waste than agree to him going???
I hope you can reflect on some on these responses with a clear mind and see that in the future if you want something to happen you need to take action, not watch and wait

Yes or at least a token payment or a bunch of flowers or something

True - but it was used in the end so why shouldn't she get paid for it?

If it was unused then that would have been annoying, but her sister and her BF got use out of something and so they are in the "credit" for free (win-win) - whereas OP didnt get either the enjoyment of the night, OR the money (lose-lose)

No - if you wanted payment for it you should have followed up with DS1 much earlier than you actually did.

Would you have paid for your sister’s ticket if she couldn’t go because you’d dropped out on her? Come on now.

You were flaky and let your sisters down by agreeing to go to an event with them when you weren't actually free and then choosing the other thing as a better option.

If you wanted to sell the ticket if niece didn't want it you should have just said 'let me know by this date and I'll try sell it if she doesn't want it', not leave it open ended not giving a deadline at all.

I doubt the boyfriend would have gone if he'd had to pay for it given that he wasn't fussed enough to want to go in the first place. YABU.

It doesn’t sound like you made any attempt to sell the ticket, so otherwise it would have just gone to waste. Surely it makes no difference to you that he went, seeing as you weren’t selling it anyway?

I'd just be glad it wasn't going to waste, right it off

If he hadn’t of gone then you wouldn’t have anything for it either.
You did nothing about it and just left it so couldn’t have been too bothered.

OP can also take some responsibility and have said you have to X date to check or I am selling it.
She never. So yes that is the OP fault.
