With all due respect
DSA-IAH, this thread is beating a dead horse. I don't want to sound like a cratchety-old FT'er, but the Terminal B, especially the B84 complaint has been voiced here since the beginning of time...zzzzzzzzz.
Do I hate it? Absolutely!
Have I missed flights at B84 due to GA's yelling boarding instructions rather than using the P.A. system like they do at WN

? Yes!
Is it hot, smelly, with funky bathrooms and no concessions? You betcha!
However, remember that this area is a bit smaller than normal right now due to the renovations going on, and it will re-open drastically in a couple of months with new restrooms, concessions, somewhat seperated waiting areas and
NEW air conditioning (rather than the "re-used" jetway ac's that are cut and tied to the existing building).
Point being, don't fret, it's still better than a CRJ, a turboprop, or flying WN!!
