In the UK at least, I know that Spantax did a lot of work for Intasun. That might have changed when Air Europa came along with its brand-new 733s. As already stated, Hispania provided significant capacity for Thomson where Britannia Airways was absent and I believe Spanair worked for Thomson too. If the likes of Futura, Universair et al had contracts with any smaller British tour operators, I'm not aware of them.
