(CNN) - Airlines tell us to fly the friendly skies, and a new survey shows, air travel is getting friendlier.
Fewer Americans are finding things to gripe about when it comes to airlines.
For some people, flying means long lines, potential delays, and squished seating.
But these days, the experience appears to be getting better.
The government said there were about 10,000 complaints from passengers so far this year.
That's down 14 percent from last year.
The airline with the best record is Southwest, followed by Alaska Airlines, Delta, JetBlue and Air Tran.
Frontier was the worst having the highest rate of complaints, followed by United.
But both of those carriers have been going through transitions.
Frontier is becoming an ultra low cost airline with new policies, and United is recently merged with Continental.
But United is getting a lot better. It gets the award for "most improved."
Complaints about reservations and ticketing at united plunged 30 percent this year.
Airline mergers are difficult, and complaints usually shoot up when two companies combine.
Overall, Americans' number one gripe when flying has to do with flight problems like cancellations, delays, and missed connections.
