I agree the terminal is straining at the seams at particular times of the day and something needs to be done quickly if the growth is to continue.
In the short term, maybe offering incentives for airlines to use the terminal at less busy times may be a short term answer. This would then enable limited growth in pax numbers with the facilities we currently have. The terminal isn't particularly pushed in the evening hours for departures (post 6pm).
2008 should push LBA quite comfortably through the 3m mark with the current route expansions which have been confirmed (by Jet2). Still find it amazing that the airport haven't announced offically the new Shaheen flights - surely this new route would be something they would want to shout about quite loudly ?
