A geomagnetic storm spawned by a giant eruption of gas on the sun reached the Earth's upper atmosphere on Friday, interfering with high-frequency airline communications but causing no major problems, federal officials said.

In this paper, we propose a bi-level air transport market model which can handle the shape of network, airfare and service frequency as airline's control variables and passenger's behavior.
A case study demonstrates the feasibility of applying the proposed models and elucidates how interactive multiobjective programming models may be applied to determine flight frequencies for airline code-share alliance networks.
The survey looked at the three factors of most importance to airline passengers: frequency, travel time and price, for journeys outside rush-hour.
The manager ran outside his office in Concourse B after hearing the report about the sighting on an internal airline radio frequency.
Lingering concerns about frequency of service and airlines' commitments to the market also deter use, he said.
The airlines and frequency vary with the season, and there are often cancellations due to bad weather.
In June 2008, citing hikes in the price of oil and the need to contain operational costs, the airline reduced frequencies across its network and announced an increase in airfares to offset the increased costs, whilst taking advantage of the lower cost of jet fuel at Delhi, Kolkata and Bangkok airports.
He also suggested going online to check an airline's flight frequency schedule since not all airlines offered daily flights to international destinations.
"You'll have the best shot," he said, "if you have a good knowledge of the airline hubs, the frequency of the flights and the flight capacities.
