Which airlines deliver at the highest frequency?

Airlines in the U.S. delivered 1.3 billion miles in 2015, according to new data released by AirlineRatings.com.

That’s a 15% increase over 2014, when 1.1 billion miles were delivered.

That means the country’s carriers are getting more business on average every year, according the site.

The increase comes as more airlines are trying to make inroads in connecting customers and cutting travel costs.

The new data also shows how far the country has come in recent years in terms of frequency and how many flights are in operation at any given time.

Airlines were ranked in terms, not the average, of the number of flights each carrier delivers in any given year.

The U.A.E. had the second-highest number of air routes per 100,000 people in 2015 with 692, and the U,S.

had third with 685.

The United Kingdom was last with 574.

Airlines are getting a boost from their recent merger.

In 2014, the merger was approved by the Federal Aviation Administration.

In 2015, the FAA allowed the merger to go forward, but the deal was never finalized.

This year, the agency will need to approve it again.

It will then be up to the FAA to give final approval to the merger and the carriers to follow through with the merger.

A new airline merger is expected to take place sometime in 2019.
