Help needed on what I can/can't expect by way of a refund??

We're flying out to Orlando from Manchester in October. I booked 5 x PE seats for us.

Unfortunately my adult son can't go now, due to a new job starting in early October with an extended training period.

I contacted VA about cancelling and what I could expect by way of a refund.yes. it's a non-refundable ticket, so I was looking for clarification.

The guy told me he'd do the form for me...tres kind! - and we went through it. 13 days later, no e-mails. I rang yesterday ( the 6th ) to be told to ring back Monday as there's no sign of anything having been done, hey ho

Could any kind soul give me an idea of what if anything I can expect / am entitled to etc. I ask since in my conversations with VA I've been told ' guesstimates' from around £102 to £212 as a refund of taxes???

I honestly don't have a clue..... and while I'm sure VA won't have me over I'd just like to know what the situation should be.

TIA

You will get back the airport fees and government fees and taxes less admin fee which I think is £30.

APD in PE is £150 and the rest around £50 (though I've not looked at the actual fare breakdown which you could do via a dummy booking)

Thank you..... and pretty dam' close £181.82 from VA + an 'extra' £50 by way of apology for the delay.
