I take it these new routes to Las Vegas and Barcelona are in preparation for the pull-out of BA from Lgw much discussed on this thread?
LGW-BCN is hardly a "new" route as it was suspended not too long, it was certainly flown from 2005-2009 and possibly thereafter, so not sure why given the state of the Spanish economy they think it's worth another go. Iberia don't even have a large presence there so not much in the way of IAG presence. I don't see BA pulling long haul from LGW but short haul just seems to be getting smaller each year, remember every time a "new" route is flown, another route is downsized or dropped as that fleet size is only going one way at the moment.
