I don't think it would matter one jot if airlines were viewing your comments or not. I would be very surprised if the commercial/route development teams of every UK airline don't look at stats for every airport in country, afterall if they didn't then then would be failing in their roles. There's a reason why there aren't many airlines in BOH, just the same as there isn't in CWL/DSA & alot of other regional airports, it's because it simply isn't commercially viable, if it was then airlines would flood into there in abundance.
