Upgraded: Business reasons for business travel
Take this with a grain of salt the size of a Rubik’s Cube, but the U.S. Travel Association announced that research they commissioned shows that “every dollar invested in business travel generates an average $12.50 in increased revenue and $3.80 in new profits.” Slightly more specifically, “Executives cited customer meetings as having the greatest returns, approximately $15-$19.99 per dollar invested, with conference and trade show participation returns ranging from $4-$5.99 per dollar invested.” The entire report — which is based on a survey of perceptions of the impact of travel — is available here.

Upgraded: Baggage allowances on Gulf Air
This isn’t something you’ll see in North America anytime soon: Gulf Air is raising the weight limits for passengers with (complimentary!) checked baggage, effective October 1, 2009. And the increases aren’t small: +10 kg (22 lbs), in each class. That raises the total weight limits for First, Business and Economy to 50 kg, 40 kg, and 30 kg, respectively. Silver-level frequent fliers in Gulf Air’s frequent flyer program get another 15 kg; gold members get another 20 kg. Individual bags are still limited to a whopping 32kg (70 lbs) each.

Upgraded: Virgin Atlantic’s website
Sure, airline websites have been selling hotel reservations and rental cars. But now Virgin Atlantic is trying to go further by offering “add-ons” like passports and visas. Services are provided by CIBT, either via the Virgin website or call center. (Or, perhaps more accurately, centre.)

Upgraded: Punishments for abusive passengers in-flight
The FAA is increasing the size of the penalties it levies against unruly passengers, like the man who “dropped his pants and exposed himself to the female passenger sitting next to him, then punched her, according to an FBI affidavit.” Good.
