I'm sorry to say that my experiences of using MJV have been very different to those of tangocharlie. Whilst I love the fact that there are palm trees on the walk from the aircraft parking stands to the arrivals hall, which includes a wait in the glorious Costa Calida sun, the departure lounge is an absolute shambles with a few vending machines, and one little cafe. Add to that a basic lack of seats, no room for passengers to queue which results in huge snakes around the lounge area, and the shambles in the check-in area (poor signage & organisation at the best of times), I'd say MJV has a little way to go before I'd say it can handle these new flights well.
It is a shame we've (WW) pulled out of MJV because the staff there were lovely and we seemed to have a loyal little following, but there wasn't market for two airlines on the EMAMJV route.
