I've never flown on any of them but I do remember. The earlier ones such as Air Spain and Transeuropa didn't use Leeds Bradford but, after the runway extension opened in 1984, they began to appear. Aviaco, Iberia, Futura, Universair, Oasis, Hispania, Viva, Spanair, Spantax, Iberworld, Volar, LTE Espana. And Air Europa, which is still with us! In the UK at least, such airlines were more often seen at the smaller airports operating flights for Thomson Holidays, Intasun and so on where the likes of Britannia, Air Europe and Monarch didn't have a base.
