I often charter planes, flying film crews around the country. Usually jets run twice the price per passenger as turbo props.

The general rule of thumb for jets is about $1,500/hour for a small jet (up to about 8 passengers) and about the same for a prop that can hold up to 19 passengers.

For a jet that can hold up to 20 or so passengers you're looking at $4,500 to $7,000 per hour.

Are you going to need a roundtrip? And if yes, are you going to keep the plane & crew in Wichita for the duration of your wedding? This can also get expensive. Or you'll have to pay for them to deadhead back to IAH, unless they can round up some one-way business back to Houston.

I would call around, I'm sure you can do much better with a charter company based at IAH.

A good place to start is to call the General Aviation phone at IAH and ask for some recommendations.
