I think MLB suffers from too many other airports within a reasonable drive.
Of course MCO
pulls traffic with high volume of flights and carriers (including LFC). SFB
has some traffic as well. You've got DAB
to the north and PBI
to the south. Just not that much high yield consistent traffic to justify many more seats that you have now.
I, too, enjoy using MLB. I can recall flying out of MLB on EA
back in the day... good times.
I want to live in an old and converted 727...
