They are all Boeing 737s
Southwest airlines only has Boeing 737s. Nothing else.
Typically Boeing 737s have a 2 class seating arrangement but they may sometimes also have a 1 class seating arrangement. It depends on the airline.
As of October 2014, they are flying Airbus 319, 320, 321, 330, 340 and also Boeing 737s
Depending on the exact type, the cruising speed is about 475 knots, or 545 miles per hour.
The engines are perfectly round... the nacelles are not! The first 737s (737-100 and 737-200) had turbojet engines that had a small diameter. When Boeing developed the 737-300/-400/-500s, they had to fit turbofans underneath the wings that were much larger in diameter than the turbojets. That's why they "cut" the nacelle like this, to provide sufficient ground clearance. The nacelles on the 737-600 to 737-900 have a similar "cut" but not that pronounced (different nacelle design). skal
Ryannair only operate Boeing 737s. They lease them for a fixed period, then return them for a new leased aircraft. Therefore you will see a variety of series 700 and series 800 models, but all will be a 737.
Southwest Airlines' fleet currently consists of 570 aircraft in service. These are all Boeing 737s, and include 300, 500, 700 and 800 variants. They have placed orders for a further 338 aircraft, to be added to the fleet at some point in the future.
No and in fact they gained more with the merger with Continental.
Over 7,400 have been built so far.
The Boeing 737 is one of the most used aircrafts in the world. The price of a single Boeing 737 is around $51.5 million to $87 million.737-700: US$74.8 million737-800: US$89.1 million737-900ER: US$94.6 millionThese are the Boeing list prices, but airlines often can still receive large discounts or other deals.The cost of a Boeing 737 ranges throughout models and configurations. The "Next Generation" Boeing 737s (600 - 900 versions) have a price range between 50 and 85 million dollars US.Numbers for 2008 are as follows:737-100 = US $32 million; 737- NG = US $50-85 million737 Family 2008Model $ Millions737-60051.5 -- 58.5737-70058.5 -- 69.5737-80072.5 -- 81.0737-900ER76.0 -- 87.0It costs about $58 million US dollars.
A 737-700ER surely can, but other 737s just can´t pull such a leg.
