I've been in to fourteen class bravo airports, most in small airplanes, all in nothing larger than a King Air. Be willing to keep your speed up on final, listen carefully, reply promptly, and follow instructions, and you'll get in anywhere without much trouble at all.
I've visited: EWR, BWI, IAD, CLT, ATL, MEM, MCI, DTW, PIT, IAH, JFK, PHL, DAL, HOU.
I will add #15 on Monday ... MIA.
