Yes it's true one flight did land on 14 but as far as I can remember the pilot got a slapped wrist for his troubles as 14 was too short a landing run for company ops. He proved them wrong. Shame we don't see many of the heavies anymore but the fact remains the runway is marginal for any realistic load for long haul.
Otherwise why would BHX be extending it's 8547ft/2605m runway which is already nearly 1200ft longer than LBA by another 400m? Lets not forget they also dont have a hill at one end and are not 680ft above sea level. BHX regularly gets 772/773s at the moment but they are obviously serious about long haul.
LBA however are making the best of what they have without a major spend on the runway. Thank goodness the A310 is still in operation, even the A330 would be feasable on a DUBAI but you are again on the margins.
If LBA really want to attract growth in long haul they will have to do some work on the runway. I don't see it happening any time soon.At least Bridgepoint are attempting to sort the terminal out.
