I didn't witness the infamous Spantax episode that Flightrider is referring to. I did see an extremely late rotation off RW32 at LBA by an Aviogenex 732. I didn't think it was going to get airborne; thankfully, it did but it seemed like it only cleared the 32 localiser by a matter of feet!
In fact, I don't remember any noteworthy incidents with any Spanish charter airlines apart from a Jordanian-registered A320 attempting to mimic a TriStar incident from several years before. Can't really blame the Spaniards for that one - wet lease and all that. R/T standards could be wanting though and clearance readbacks sometimes took a few attempts.
Apart from Air Europa, the Spanish charter airlines never seemed to last very long.
