All passengers aboard a Delta Airlines plane have been screened by the FBI and allowed to continue on their way after a more than four-hour delay.

Delta Flight 1500, with 151 passengers, was forced to land in a remote corner of Denver International Airport at about 4:40 p.m. because of a threatening note.

DIA announced on Twitter at 9 p.m. that all the passengers had been released to pick up their luggage.

Aaron Baratz, a passenger, told The Denver Post via Twitter that the passengers were taken from the plane by bus. They were not allowed to open overhead compartments and retrieve any bags.

Authorities, including K-9 units, searched and secured the plane.

Other flights are being delayed because of the incident, passengers were reporting over social media.

DIA officials said they were not aware of any delays and said they had been in contact with the airline.

This story will be updated as more information becomes available.

DENVER, April 19 (UPI) — FBI officials questioned passengers on board Delta Flight 1500 and searched the Boeing 737 after a note with a bomb threat was discovered on the plane. No bomb was found.

The pilot of the plane notified air traffic control of the threat, which was found on a note in the rear galley of the plane by a flight attendant.

“Flight 1500 now declaring an emergency at this time. We have a written threat aboard the aircraft,” the pilot said. “Our flight attendant found a note indicating there was a bomb onboard towards the rear of the aircraft.”

The plane, which was en route to Denver from Detroit, arrived safely at Denver International Airport and was taken to a remote location at the airport for screening.

“The FBI came on board the plane and asked, of course, did anybody leave the note. They said there was a piece of paper in the back with the word bomb written on it,” said passenger Joe Vance.

One passenger, Tone Sevy tweeted information about the search and photos as he awaited heading back to the terminal.

“Why did it take so long? What was the real holdup here? What were they really looking for?” asked Jace Booher, according to CNN affiliate KDVR.

A law enforcement official told CNN that a bomb threat found written on a note prompted the security screening after the plane landed at Denver International Airport.

The 737 aircraft, which was carrying 151 passengers and six crew members, landed safely at 4:40 p.m. MT as scheduled, said Russell Cason, a spokesman for Delta.

The plane was taken to a remote location at the airport for the screening.

Security threat reported on Detroit-Denver Delta flight

April 19, 2014

A Delta Airlines flight that landed at a Denver airport was directed to a remote taxiway after an unspecified “potential security threat” onboard and passengers were ushered off the plane, interviewed and the scene secured, officials said.

Flight 1500, a Boeing 737 with 151 passengers and six crew, landed roughly on time at Denver International Airport from Detroit Metropolitan Airport at about 4.40pm Mountain Time (2240 GMT), airline spokesman Russell Cason said.

The passengers were quickly sent off the plane without their luggage and taken by bus to a separate part of the airport where they were being interviewed by FBI officials. There were no reports of injury.

Flight 1500 had a “potential security threat onboard the aircraft,” Denver airport spokeswoman Julie Smith said, adding that all other airport operations were normal.

A local ABC News affiliate reported that a flight attendant found a note with a bomb threat. An FBI spokesman in Denver, Dave Joly, said he could not confirm that report, and said that authorities were investigating the “security concern” by screening passengers, luggage, and the plane.

“The majority of the Delta Flight 1500 passengers have been allowed to claim their luggage and continue with their travel plans,” Joly said late yesterday.

Joly would not give details of any detentions or arrests, threat credibility, or say if a bomb had been located. Smith, with Denver airport, said late yesterday the “event” had been “secured.”

Passenger Aaron Baratz told the Denver Post he and others were not allowed to open overhead luggage compartments to retrieve bags.

Tone Sevy, another passenger, posted a photograph on Twitter showing more than a dozen passengers returning to the idled jet on an empty stretch of runway to gather belongings. He said police with a dog were checking travellers, the buses, and the plane.

“Getting personal stuff off plane almost 2 hours later,” Sevy tweeted. “Happy we are all safe.” – Reuters, April 19, 2014

Economy class passengers bound for the US, Canada and Mexico can now check in two pieces of baggage for free on Air France-KLM and Delta Airlines.

The maximum permissible weight per baggage has been set at 23 kg, as per a press statement. Earlier, the free allowance for economy class passengers was capped at 23 kg for one piece of baggage.

“We are constantly looking at ways to fulfil the needs of our customers and provide the best possible service to them. Revising our baggage allowance to North America is one such step in that direction,” said Yeshwant Pawar, General Manager, Air France-KLM.

Frequent passengers of Air France-KLM and Delta can carry an additional check-in bag above their permissible baggage allowance limit.

There is no change to the per-person baggage allowance for passengers flying in the Premium Economy and Business Class, the company said.

Analysts said that the intense competition from full services West Asian carriers, Emirates, Qatar, Etihad and others, has prompted Western airlines to raise baggage allowance, a stark departure from the decade long strategy of compelling passengers to travel light or pay steep fees. Most of the West Asian carriers allow passengers from India to carry two pieces of check-in baggage.

NEW YORK (TheStreet) — I don’t ever remember airline stocks as momentum plays, but the seven we profile today are flying at elevated altitudes. Five are achieving parabolic orbits that will be difficult to sustain.

Lately it seems like airline stocks have been headed for the stratosphere, but they will likely return to “cruising altitude” — their 200-day simple moving averages — at some point this year.

We crunched the numbers to help you decide if and when to invest. Here are the profiles for seven airlines, and our two “Crunching the Numbers” tables follow.

The weekly chart is positive but overbought, with its five-week MMA at $88.20. This parabolic began in December 2009, when the stock moved above its 200-week SMA, now at $43.53. Quarterly and semiannual value levels are $86.98 and $71.68, with a monthly pivot at $92.91 and this week’s risky level at $99.23.
