Two years ago it cost my friends almost £1000 to fly their cat and dog to Torremolinos for a six month stay from Glasgow. It was also discovered that they would have to go to Manchester to pick them up on their return to Glasgow becausevthe facilities were not available to let them re-enter the departure airport. If you're flying from Manchester I'd imagine you could flyback to there. The £1000 included they pet passprot and all the jags etc that were needed. I'm not sure if you could do it for a short holiday as I remember they could not return to Uk for at least six months if you check with the DEFRA web site it will tell you on there.
