IF you're the kind of business traveller vacation rentals in paby owner who loves flights—especially super-long ones—I vacation rentals in paby owner have some bad news: Singapore Airlines' flights 21 and 22, the longest commercial services in the world, are scheduled for cancellation. The two all-business-class flights, which operate between Singapore and Newark, New Jersey, take around 19 hours and cover 9,525 miles (15,329 km). But late last month, Singapore airlines announced that it would be cancelling the services, along with another between Singapore and Los Angeles that is almost as long.
The title for the world's longest flight, reports Ben Mutzabaugh of USA Today , will now shift to Qantas, which operates vacation rentals in paby owner a 8,576-mile service between Sydney and Dallas. Singapore Airlines is scrapping its record-holding services as part of a massive new deal with Airbus. Under the terms of the agreement, vacation rentals in paby owner Singapore will get five new A380s and 20 new A350s, and the manufacturer will buy back the A340-500s that the airline uses on its super-long-haul routes. But those explanations will do little to comfort the business travellers and long-haul-flight enthusiasts who will now be missing out. CNN spoke to one of them :
Business traveller Charles Yap is a big fan of this route because it avoids a connection in Germany, which he says saves six hours. All 100 seats aboard the flight are business class. Add hundreds of in-flight movie choices, and longhaul travel isn't so bad for this Discovery Channel executive.
As CNN notes , high fuel prices are the underlying vacation rentals in paby owner force that's driving these cancellations. As prices have risen, twin-engine planes such as the A350, the Boeing vacation rentals in paby owner 777 and the new 787 Dreamliner have come to dominate super-long-haul vacation rentals in paby owner routes, displacing gas-guzzling four-engine planes. (The A340, which Singapore Airlines was using on the Newark route, is a four-engine plane.) For 19-hour flights to return, America's Federal Aviation Administration would probably have to do away with a longstanding rule that requires two-engine planes to stay within a certain distance of runways where they can land in case of trouble. (Four-engine planes are not subject to this rule.) Engines are leaps and bounds more reliable than they were decades vacation rentals in paby owner ago, and modern two-engine planes can fly on one engine without too much trouble. It's worth taking another look at the rule.
1. Yes, C is more profitable than Y on a per seat basis, but you can get more Y seats on a plane. SQ21 has 100 C seats, vs a typical 42C-225Y or 12F-42C-204Y configuration on A340-500's. So comparing vacation rentals in paby owner the first two, there are 58 extra C seats on SQ to generate the same revenue for 225 Y seats, a ratio of 3.88. On SQ, Y (SIN-JFK) typically costs US$2,600, and C (SIN-EWR) about US$7,000 or only 2.69x, so Y already has an edge in terms of yield, which means that you need to fly much fuller on the all business versus a two class configuration.
"modern two-engine vacation rentals in paby owner planes can fly on one engine without too much trouble" -- spoken like a true armchair journalist who's never looked down 35,000 feet at the Pacific ocean and considered the implications of being four hours of flight time to the safety of the nearest landfall, or been aboard any of hundreds of commercial flights that actually experienced vacation rentals in paby owner an in-flight engine outage over the last decade.
Still, it is true that with only one engine operational, a commercial twin can still fly to the scene of the accident - how comforting that airlines choose fuel economy of the twin over critical system redundancy and flight safety.
Indeed, it's not 4 engine vs 2 engine but just being more fuel efficient overall. And the reason ultra-long flights stop making sense at times of high fuel prices is that they burn an inordinate percentage of their overall fuel load just getting the fuel required for the rest of the journey off the ground.
An uninformed hotchpotch of an article written by a clueless author with no idea about how the airline industry works nor how planes work. The author claims SIA scrapped the flights because of poor fuel economy of the A340-500s used on these routes, because vacation rentals in paby owner they are 4-engined planes. If this were true, SIA could simply have replaced them with twin-engined alternatives and retained the routes. The real reason for the cancellation of the routes is that there is simply not enough market demand from passengers willing to pay the premium fares for a non-stop flight on these routes.
vacation rentals in paby owner If you're flying from the east coast of the US to the Far East or Australia, this flight gives you the choice of one very long-haul trip on a world class airline and access vacation rentals in paby owner to a superb vacation rentals in paby owner business class lounge at Changi in Singapore. The layout of the plane is 1-2-1 with big flat beds and lots of extra room. Because there are only 100 or so people of the flight it boards very quickly and the cabin interior doesn't get rank.
While SIN-LAX and SIN-EWR non-stop routes are ending this month, the actual announcement that SQ was dropping the two routes was made in October vacation rentals in paby owner 2012, as per the date on the press release, rather than "late last month" as you wrote.
The latest version of a 777 has a similar payload capacity as a 747-400 but is much more fuel efficient. I understand the fuel burn on the HKG-LHR is 40 tonnes less for the 777. I think the ETOPS rule is a maximum of 3 hours from a runway and does not apply simply to trans-oceanic flights.
The ETOPS claims are truly absurd. The author claims that 2-engined planes could not fly this route because of the ETOPS rules that require 2-engine planes to stay within a certain distance of landing strips. However the EWR-SIN has no problem meeting ETOPS rules; it takes a similar path to other routes like EWR-HKG and SIN-FRA-JFK which are routinely operated by two-engined planes.
On a Delta flight Atlanta to Memphis, lost the port engine about 15 min after departure. We made a VERY slow turn to the right, flew back until we must have been at least 20 miles NE of the airport, vacation rentals in paby owner made another slow right, and made the smoothest vacation rentals in paby owner landing back in Atlanta I have ever experienced in a commercial aircraft. Guess a lot depends on who is driving.
Before the age of non-stop flights between everwhere in the late 1980s, intercontinental flights (TKY-LHR, TKY-NYC) required a refuelling stopover (Anchorage, Alaska, was the preferred stopover for BOTH those routes due to the Iron Curtain) and routinely exceeded 17 hours, with some routes as long as 20 (Tokyo to Rome via Hong Kong and Bahrain/Doha/Abu Dhabi) hours.
This is patently false. I shouldn't think the route is that different from the one used by Cathay vacation rentals in paby owner Pacific HKG-JFK on a Boeing 777-300ER. From SIN, it could easily be done on a twin engine Boeing 777-200LR
