Global air travel volume in November increased 6 percent year over year,

the International Air Transport Association reported on Thursday. Domestic travel, particularly within China, has accounted for much of the growth, while international air travel volume growth was below its long-run average in November. Though lower oil prices should help boost air travel demand this year, “the gradual easing in business confidence over the final third of 2014 has weighed on international travel and may continue to constrain the pace of expansion in the near term,” according to IATA. The association noted that domestic air volume in the United States also was on the rise in the latter months of 2014 as employment levels and consumer confidence improved.
