Hi @Rasi193

You cannot reclaim Spanish VAT from UK HMRC - they tend to get grumpy about things like that!
However, unless the invoice shows VAT I am pretty sure that scheduled flights are zero rated (UK & EU still have the same rules on this).
For GOODS, there is a mechanism for reclaiming...

For SERVICES, or where the above does not apply you can claim a refund through the EU 13th Directive process

Hope this helps.
