Occupancy rates at Columbus, Ohio, area hotels are up 6.4 percent during the first six months of 2011 compared to a year earlier, a positive sign that tourism to the city is rebounding, officials said.

Delta Air Lines is purchasing 100 Next-Generation 737-900ER (extended range) airplanes, with a list price of more than $8.5 billion, the airline said Thursday.

Delta Air Lines and Aeromexico this week announced a new partnership, which the airlines say will increase benefits for fliers.
