The most popular airlines are still not offering free air travel to travelers

NEW YORK — The top five domestic airlines still offer free domestic travel to their customers despite pressure from Congress and President Donald Trump, according to a new report by the American Customer Satisfaction Index.

“While there has been an increasing number of companies in recent years that have made the decision to eliminate travel fees for domestic customers, we found that there has not been an increase in the number of domestic customers who are willing to pay for domestic travel, as a result of the growing cost of living and the increase in air travel,” said the report.

The survey, conducted by Experian and The Aviationist last year, found that three of the five top domestic carriers, Delta, United, and United Express, offer free fares for domestic flights.

In the report, American Customer Support, an industry trade group, said that while there is a strong demand for free domestic flights, there has also been a growing number of airlines that are charging customers for domestic trips.

According to the survey, the average fare for an overnight domestic flight is $6.50, but the average for a two- or three-night domestic flight for a domestic traveler is $5.50.

There has also long been a demand for domestic destinations to offer free airport access, with many international destinations and large cities such as New York, Los Angeles, San Francisco, and Boston offering access for free.

The airlines have been offering this free access to customers since at least 2009, when Delta started offering domestic flights free of charge.

However, since then, domestic travel costs have risen rapidly.

And in 2016, the airlines started charging for domestic service.

Delta, for example, charges $200 for a one-way domestic flight and $1,600 for a return flight, compared to a $300 fare for a three-way flight.

United charges $400 for a single- or two-night return flight and a $600 fare for one- or more-night returns.

United and Delta have also recently implemented policies that require customers to pay their flights and other fees before they can fly, and that includes fees such as fuel surcharges.

The companies have also instituted a fee-for-service fee for customers who want to fly without a reservation.

For some domestic flights that are not free, a surcharge of $1 per person can be added.

American Customer Support has been pushing for changes in the airline industry, such as a national loyalty program, so that domestic travelers are more comfortable with flying with the airlines.

But the airlines have resisted.

Instead, the companies have been making concessions to their domestic customers that have created a “double standard,” according to the report released Friday.

It said that Delta and United have implemented policies to ensure that domestic customers are treated equally, but that the companies’ refusal to comply with this principle has resulted in the double standard.

United has a policy that does not require domestic customers to make a reservation or pay for a flight before flying.

Dell has been making significant concessions to domestic customers.

As part of a new contract signed with American Customer Service, Delta and Delta Air Lines announced that customers can now travel free of any additional charges, including fuel surcharge and tax surcharges, on all domestic flights within the U.S. and Puerto Rico.
