I just put up a post about JetBlue, but now I want to know, what airline believe in hauling but to the runway? I know Southwest is one of those airlines. Also, with what type of a/c, would they try this with? I know huge jetliners like A380s, 747, 777 and A340s taxi at pretty slow speeds.

Think you'll find the FOM of virtually all airlines stipulating a maximum straight-line taxi speed in the region of 20-30 knots, and 10 knots for going round corners. For contaminated taxiways, the maximum speed will be considerably reduced. Those figures are derived from the recommended practices/procedures as issued by the manufacturer, the cavaet being that if you state something different in your company FOM, the manufacturer may well impose warranty penalties.
That's not to say that sometimes a crew will elect to go a tad faster than that, but it almost certainly won't be a company sanctioned procedure, and if you regularly exceed company recommended speedlimits you may well find yourself invited to a chat with the CP sans coffee and biccies - the QAR downloads captures everything these days.
Over the eastern side of the pond, Ryanair used to have a reputation for taxiing at rather ambitous speeds, but they also seem to have come to their senses and slowed things down.

No company SOP will suggest Fast taxi beyond 20-30kts speed,depending on the type & much less around bends.
However there is always the unconcerned person that exceeds the limits to get to a point faster or make up for lost time,but at the expense of heated tires & reducing its life,more frequent tire replacements than normal.

Both airlines I've worked at have stated safe speeds for taxi to be at the discretion of the Captain. Having said that, there's no reason to go more than about 20kts. The 30 seconds it might save you will heat the brakes considerably more and also increase the chances of something bad happening.

Hey now. Not a pilot, but I've had a few airline jobs. I do distinctly recall one dressing down I received wherein I was offered coffee and doughnuts before during, and after the fact!

Yeah, this is a real concern. Most AC tires aren't even meant to be taxied more than a dozen or so miles at a time, at any speed. I imagine that number gets retarded some with greater speeds.
But alas, many pilots don't really worry about the effects of more frequent changes etc.

Quoting HAWK21M (Reply 8): Thats where company trainings matter.If the crew is given an SOP with the reasons behind the action & its savings achieved,One will see a difference in following that SOP.
Sometimes yes, sometimes no. I worked at an airline where F/O rates were concurrent with 4th year FAs. You take a pretty obviously disgusting situation like that, and you wind up with a lot of crew who just plain didn't give a rip about anything that didn't directly affect the safety of their next flight. I ended up working a lot of planes that were pretty obviously written up for things that were easily avoidable. One of the most common? "Soft" brakes. Wonder how that happens when there's more than .15" of wear pin showing...
