there are a few airlines who you can arrange flights out of ibiza back to the uk with but from looking at some of their prices its going to be very expensive for just 1 night back in the uk.

here are a couple you could try though

http://www.firstchoice.co.uk/flights/

or

http://www.thomsonfly.com

both offer flights into your chosen airport on the saturday or sunday but flights back over may be a little harder.

Easyjet do have flights from stanstead on a monday, but the others don't seem to have any flights going.

Best of luck

Thanks for that, just checked firstchoice ,awful flight time and no return flight, thomson bit better if there is no alternative will have to take thomson, competition is in wolverhampton so thought coventry, other competitors going from luton which was the next choice.
any other ideas

Have you tried Ibiza Travel Shop in Ibiza Airport? They specilise in getting people home from Ibiza. They are often used by workers on the island. Their number in ibiza is (so dial 0034 first if you are in the UK) 971 803175
