how come closer destinations have flights to each other?
how come closer destinations have flights to each other? how come Boston has Flights to NEw York City when they are 3.5 hours apart? and why does like Charlotte have flights to Spartanburg and Greensboro when they are 100 miles or less from Charlotte???? and why does Pittsburgh have flights to DC when they are driveable. Why does Baltimore have flights to Philadelphia when they are 100 miles apart? and also I am from NH And when I go to NC or SC states I always drive but why would most from my state fly?

some people dont want drive also a lot of frequenetly fliers can earn points for flying they cant do that driving they might have bussines in the airport.
2 :
100 miles or 160 km is normally the "limit" where air travel begins to be useful. It makes no sense to have a flight that is 50 miles but somewhere near and above 100 miles, it does. Remember it will take you about 2 hours to drive 100 miles (depending on roads and traffic). A flight is only about 30 minutes.
3 :
just to add from other responses, that there also has to be a reasonable demand, and could well be in smaller aircraft.

People are sometimes in a rush, business-wise, emergencies, etc. BOS-JFK/EWR, 3.5 hours apart with driving, 30-40 minutes by flying. If your relative/sibling/parent suddenly needs help or a business opportunity that requires you to be in New York as soon as possible, what do you do? Take a flight. You can drive your way down to Brazil, why not do that then? Nobody would want to bother with paying car insurance where they aren't insured in. Cars can break down on highways more than planes breaking down in airports, delaying you more time, you may need to get more rest-stops. Or some people are so dog gone tired they rather fly. Be considerate and think of these reasons, not everything is so simple and cheap as driving.
5 :
Some people would rather fly because it gets you there quicker. Also sometimes airline flights between 2 cities are really cheap so it is almost worth it to pay for the plane ticket and earn frequent flier miles versus driving, paying for gas and accumulating miles on your car.

It is possible.Many don't want to drive or just wanna loose traffic and reach a lot faster.

What's the shortest commercial flight in which an airliner gets to reach full cruising altitude

What's the shortest commercial flight in which an airliner gets to reach full cruising altitude?
How many kilometers? Dulles to JFK? Baltimore to Boston? Does the slope of that flight look like a triangle, with a constant rate of climb, or a parabola, with the rate of climb slowly tapering off?

................... there is always optimum level for the distance ................. on full load it can take up to 125 miles to climb to optimum level and the not the top altitude ............... it has to do in steps ................. as it gets lighter ................... after burning fuel ...............
2 :
More like San Francisco to Reno, or Seattle to Portland. I guess JFK to BOS would do it too. But what Spaceman says is right. It's never a parabola. Short flights would tend to have a lighter fuel load too and you wouldn't get time to earn back the fuel you burn in the climb with a long cruise, so you won't be going above about 28-29,000 feet unless traffic dictates it, any more and you'd lose ground speed and in any case you'll be coming back down in a few minutes.

he flight will reach a cruising altitude for some time. they will use smaller aircraft that most likely goes slower than u think.

Is there any transportation from Washington DC Airport to Baltimore after midnight on a weekday

Is there any transportation from Washington DC Airport to Baltimore after midnight on a weekday?
We have a flight to DC , but need to get to Baltimore, and I've looked at Metrorail, Amtrak, and something else I am not finding the right times and locations.

I don't think so. The MARC stops pretty early so Amtrak is prolly your best bet.
2 :
What airport are you flying into? I ask because there are very few flights into Washington Reagan National (the close-in airport) that late, due to noise-control regulations. Is it possible that you are flying into Washington Dulles or Marshall Washington-Baltimore Airport? The answer to your question depends in part upon which airport you'll be arriving at.

Are plane tickets more expensive if purchased on a weekend

Are plane tickets more expensive if purchased on a weekend?
I'm looking to purchase flight tickets to Baltimore on the weekend of Feb.21 -25. I've been watching the prices and seems on weekends the cost increases but then goes back down on mondays. Is this typical?

It happens, but I wouldn't say typical. Maybe they're selling out faster on the weekend too.
2 :
yes,and the sad thing is that most airlines consider week-ends to run from thursday to monday.
3 :
A lot depends on where you are flying, and also on where you are buying. Also, not clear: do you mean that the fares are higher for flights on the weekend? Or that the fares actrually jump up on Friday and back down on Monday no matter what date you want to fly? Many routes cost more on weekends because they are popular with family travellers, or vacationers. Business-heavy routes tend to be cheaper on weekends.
