Business travelers still aren't coming back to the good seats, despite airlines' best efforts. FareCompare.com reports that many business class tickets to Europe are going to be 33% to 66% cheaper this fall relative to last year. Companies are being careful with their cash – which means stacking people in coach rather than giving them a little leg room on overseas flights. With back-of-the-plane tickets going for a quarter of the price (or less) than their business class equivalents, this isn't exactly shocking.

On Wednesday, Delta's (NYSE: DAL) cheapest NYC-to-London's cheapest roundtrip coach fare was $716 (for an October 23 departure and October 30 return), according to a report in USA Today. To take the same trip in business class, you were looking at a hefty $4,634. So, even though prices are down year-over-year, it doesn't mean that business travelers are being allowed to enjoy the opportunity.

Higher fuel prices and slipping demand for air travel have prompted a change. The International Air Transport Association revised its forecast of global airline losses for the year from $9 billion to $11 billion. Revenues for the air travel industry are expected to fall 15% to $455 billion worldwide. Passenger traffic is anticipated to fall by 4%, with cargo dropping 14% for the year.

Financially, IATA CEO Giovanni Bisignani says the impact of the financial crisis has been more severe than the terror attacks of eight years ago.

Airlines globally could lose $6.1 billion in 2008, on soaring oil prices and financial market dislocation, the head of the International Air Transport Association said, The Wall Street Journal reported Thursday (subscription required).

Giovanni Bisignani, managing director of the IATA, which represents 230 airlines, called the sector "a fragile industry in a crisis" and that it's "bracing for more situations of airlines collapsing," due to high fuel prices and lower revenue, The Journal reported. Further, the air travel slowdown, once thought to be contained to developed nations, has spread to global air travel's plum: Asia, he added.

Airline slowdown could hurt Boeing, Airbus

Stock analyst and frequent flier C. Leonard Bauer told BloggingStocks Thursday if the Asian hemisphere is slowing, to go along with sluggish revenue statistics in Europe and the United States, the slowdown "would have wide implications, not just for airlines, but for airplane manufacturers Boeing and Airbus."

"Further consolidation globally, was a given, particularly in nations like India, which had too many airlines even before the global economy slowed, but the concern now is that national carriers will postpone or cancel plane orders," Bauer said. "From a U.S. perspective, that could mean bad news for Boeing. And what's bad news for Boeing is bad news for the U.S economy. Airplane sales have been one of the U.S. economy's few bright spots." [Bauer added that he does not own shares in or have a rating on any airline or airplane manufacturer. However, Bauer does have frequent flier miles/points in American Airlines (NYSE: AMR).]
