Airspace Structure; Company Policy; Human Factors
Houston Approach was vectoring us for an approach to runway 12R; and we were in Class B airspace at 4000 ft MSL and 240 KIAS. Houston Approach then instructed us to descend to 3000 ft MSL and then slow to 210 KIAS. We realized this would put us under Class B airspace so we elected to slow to 200 KIAS. During the approach to runway 12R; we were told to intercept the localizer course and later cleared for the visual approach. We held our speed higher than normal prior to the ROYCE FAF to aid spacing; but then we fully configured and slowed to 118 KIAS (REF+10). At a 3 NM final (approximately 900 ft AGL) Hobby Tower asked us to increase our speed '20-30 knots' because there was a jet behind us with 70 knots of overtake. I told tower we could increase our speed by 10 knots; but any more than that would make our approach unstable. Tower then told us to do our best. We landed normally and applied fairly aggressive braking to exit the runway expeditiously.
On approach to HOU; the pilot was unable to increase his speed to accommodate faster traffic behind while remaining within stabilized approach parameters.
