I have flown so many times with spanair as i live in Spain, i've flown in their MD87, MD83 and their B767.200. I have to say: service on board is awful, and very poor. Space between seats its more than small, they fill the aircrafts with 10 more people than usual for the kind of aircraft.
On 767 no ptv on coach. Not either a good entertaiment.
Never in time, so take care not to have a connecting flight after the spanair's one.
Last november they lost my baggage on my way to Madrid form Palma and i am still waiting for them to pay me.
On December they cancelled me to flights with no reason, so i reached my final destination 16h delay, and i even didn't received an apologise for the delay.
i guess you didn't know that.
hope it helps you.
