Do you refuse to drive, and fly instead?
 

When you have a engagement or meeting that is 4 hours and 30 minutes drive away, and rail is not viable. Do you fly? Connecting once, at that.

Given that question before, I would fly but now I would consider driving.

old way/very much liked taking flights
0:30 drive to airport
0:40 check in to airport
1:00 first flight
1:00 connecting
1:00 second flight
0:20 get rental car
total: 4:30

now (if flight taken)
0:40 drive to airport
1:10 check in to airport (1:20 if very big airport)
3:00 flights (same as before
0:25 get rental car
total: 5:15

If a nonstop is available, I would fly, but with a connection involved, I would drive. While 4.5 hours spent driving is unbearably miserable, it would likely be faster.

I usually use the 4 hour rule for nonstops and the 6 hour rule for connections.

Not a problem in the Washington area, but for 4 hours of drive time, I would fly, even if it means a connection.

4 hours of drive time won't even get you outside the beltway on most days...

My husband works for the Government. With all their cost saving the won't pay for overnight accommodation but expect him to drive 3 to 4 hours to another site for a meeting of 4 to 6 hours then drive home. How unsafe. He'd prefer to fly if he could. Even if the travel time took the same, at least with flying it is relaxing instead of concentrating on the road.

I'd fly instead of drive 4 hours if I could. The only time I would not is when the airport was 3 hours away and I was going on an international flight. If the local small airport plane was delayed, I'd be in huge trouble if it got to the point where I had no time.

Yes, my family prefers to fly NY-Baltimore rather than drive 4 hours both ways in a weekend. It can be done for little more than the price of gas ($49 each way), and it saves time and energy.

I should add that the local airport is a 10 minute-ish drive for me. So my options many times are; drive 10 minute and then spend the next few hours working and hopping around the country. Or....my alternative could be to drive 5-6 hours many times.

This.

For me it depends on the type of driving. 4 hours driving in Alberta never bothered me because it was mostly flat and open with little traffic so I drove. 4 hours driving in the northeast US will make make my blood pressure soar so I fly even if it means a connection.

Drive. Assuming decent weather, anything under 10 hours I drive.

My employer requires that I utilize a rental car for car trips of more than 149 miles. The nearest rental car facility to me is the airport, and some of the cars they have on offer are very unpleasant to drive on long highway journeys.

So, I use the 149 mile rule. If it's more than 149 miles, I fly, because I'm going to the airport anyway.

I don't drive for work. Train, plane or a combination only. That said, I've almost never visited a place in this job that I can't get to by public transport (with the odd taxi).

Also keep in mind that the more and longer you drive, the more likely you will encounter conditions that result in an accident or ticket. If this is for business, this is a liability that endangers your personal driving record and insurance rates.

Cost factors in for me too. I had a project in Greenville, NC. Not a fun drive from Charlotte (~4 hours), but the flight is in a regional jet and 7-day fares were usually in the $700 range. Needless to say I drove.
