The was first ordered in , and the last was delivered in Its extended-range model, the ER, entered service in The was first ordered in and was followed by its extended-range model, first delivered in The ER, which first flew in , can carry passengers in a two-class configuration more than 7, miles 11, kilometers.
The family also includes the Freighter, based on the ER fuselage, rolled out in May and first delivered in October Both seat counts include the crew rest seats.
The ER model stretched The ER also featured improved electrical and air-conditioning systems, increased takeoff weight, "raked" wingtips to increase fuel efficiency, and a new style interior. Delta took delivery of its first ER on August 11, , and began replacing L s on high-volume domestic flights:.
Delta received its th jet from Boeing on October 23, It was the sixth ER delivered to Delta in On March 27, , Delta announced plans to convert its entire ER fleet to an international configuration, featuring a BusinessElite cabin.
The ER also continued to fly high-volume domestic flights. Special Liveries Delta has placed commemorative markings on a number of s in its fleet:. The last of Delta's domestic Boeing fleet retired on June 3, Before this, capacity and jet performance had been more important considerations.
Following a ten-month test program with six aircraft, the first entered service in September with United Airlines. The was originally proposed with three different variants. The smaller was dropped before construction, with the offering similar capacity. The was, therefore, the only variant offered at launch. There was another difference with some early s in the cockpit. The Airbus A as the first widebody twin also had a three-person cockpit.
This caused a few concerns from airlines, with crew used to three or more. United Airlines initially asked for a version with a three-person cockpit but accepted two once it was deemed safe in the US.
Ansett Australia, however, stood by a request for three-person cockpits mainly due to pilot union demands and was the only airline to receive early s configured this way. The s and s were still very early days for twin-engine operations. And there had been doubt during development, with the MR proposed as a three-engine alternative mainly to get around twin restrictions at the time. At launch, the was restricted to operating no more than 90 minutes from a diversion airport. This prevented twins from operating commercial routes over the Atlantic and, of course, elsewhere too.
ETOPS regulations changed this from the mids. ETOPS allowed aircraft to fly up to two hours from a suitable diversion airport. This opened up transatlantic routes to the and marked the start of new possibilities for twins.
The became the first aircraft to be certified for this in After moving through several variants, the remains in production today — in both passenger and cargo configurations. The original was first upgraded within its first year, with the extended range variant ER. This kept the same fuselage design but offered increased payload and additional fuel capacity. Its range was increased to 6, nautical miles 11, kilometers , from the s 3, nautical miles 7, kilometers.
The ER was popular with US airlines, but also more internationally. Ethiopian Airlines placed the first order in , and the type entered service with El Al in There are three variants of the , which were launched on three separate occasions.
Although there are a total of three variants, several versions have been produced. The first model of the , and was launched in and entered service with United Airlines in The typically is outfitted with seats in a 3-class layout or in a 2-class layout.
All models have a capacity limit of due to exit-door limitations. The ER extended-range variant was first delivered to El Al in It became the first to complete a nonstop transatlantic journey, and broke the flying distance record for twinjet airliners several times. Although the ER has no direct replacement, it is expected to be replaced indirectly in Boeing's lineup by the As of August , s and ERs had been delivered with no unfilled orders remaining.
The is a lengthened ordered by Japan Airlines in The ER is the extended-range version of the It first flew in and received its first commercial orders when American Airlines purchased several in The aircraft entered service with AA in The ER has a minimum takeoff run of around 6, ft 1, m , and a maximum of 7, ft 2, m. The F is the air freight version of the ER, first ordered by United Parcel Service in and delivered in Due to its unique fuselage width of 15 ft 6 in, it is unable to carry ordinary Unit Load Devices , and instead has to use specially designed air freight containers and pallets.
This model has three doors on the main deck plus two on the lower deck. Of the three doors on top, two are at the front, and one is at the rear right side. The two lower doors comprise of one at the right front and one at the rear left. The 's direct competitor from Airbus is the A The is expected to be replaced by the in Boeing's lineup.
This includes orders all delivered for the , orders for the ER delivered , and 82 orders for the F 49 delivered. The ER was stretched It also saw a wingspan increase of
