cokie - I assume your question refers to windspeed along the runway rather than across. I have landed 737s with gusting 65kts and the major problem is taxying when you turn across the wind especially if the surface is at all slippery. That, as 'Intruder' says, tends to put a top end on it. Strong winds can also cause havoc on the parking stands. I was turned quite a few degrees on stand by a strong wind and I have seen a badly chocked BA jumbo turned 45 degrees.
As 'SR' says, until you try to turn out of the wind or open anything, actual wind speed is not really a problem for a jetliner as they are designed to fly at high (relative) wind speeds.
