Plane Trips are Porthole to Porthole Travel Tip

This is the main reason I stay on the ground.

I did fly to Israel and back to Greece, but there was no choice. I left the Hostel in Tel Aviv at 4 AM, arrived at the Hostel in Athens 12 pm.

Eight hours travel time, 2 1/2 hours in the air.

I should be on the ground for the next few years in Eastern Europe, at sometime cross Russia to Asia.

I find it totally more expensive to fly, too.

True indeed its better to travel by land if its only in a short distance journey but its more comfortable in the air if its a long distance.

I know that precise English is not your goal, nor should it be, however just for the record, its "portal to portal." Not to take away from your point, which is quite correct as most travelers know.

Three hours by air is about 1500 statute miles. I defy you to find any form of transportation that can cover that amount of distance. You have a real point about that if the trip is under 500 miles though. I recently flew 466 miles in 4 hours door-to-door, and this is with a toddler and checked bags. Everything had to happen perfectly thought for that to happen, but we do it about every 2-3 months.
Flying is expensive, but only if your time is worth nothing. I roughly budget my time at $30 per hour, so a 10 hour bus ride "costs" me $300 of my time (any time you are doing one thing while wanting to do something else). That 10 hour bus ride is about 5 hours door-to-door, or a $150 savings of "wasted" time.
(I base the cost of my time on about 80% of my salary).

If I do everything perfect than air travel is great. I can make 1000's of mistakes with a bus trip and still keep in budget.

Wages, if a person is making over 25 dollars per hour and is self employed, then planes become better. I am not sure which is more comfortable, I am always more beat after 24 hours of plane than 24 hours of bus.
