Do you remember last summer , when angry travelers were urging the government to do something about airline customer service ? Airlines     36     to improve , and they adopted (采用)new standards just before Christmas .    37     as another summer nears , plenty of     38    

travelers don’t see much improvement in customer     39     overall .

This month , the Department of Transportation’s (DOT) office will publish its first critical   40      

on whether airlines are     41     their promises . One survey（调查）suggests problems : the number of     42     to the DOT about the top 10 airlines in the first     43     rose 89% from a year ago .

Hit last summer by passenger complaints  and the threat (威慑)of consumer-protection laws by the    44      , 14 airlines     45     to adopt a set of basic customer-service standards called Customers First . The “12 promises” to passengers were introduced     46     a mjor effort to improve service . Since then , airlines have been redesigning websites , retraining employees and upgrading technology .

Recently , DOT inspector general Kenneth Mead , at McCain’s request , sent 20 examiners to airports to     47     whether each airline is doing what it promised . Mead warns travelers shouldn’t    48      too much . Most of the promises are    49      better communication with customers , not problems with flights .

“Passengers should show more understanding to airlines about their     50     to better air service .” Spokeswoman Shelly Sasson says . “And when     51     are made , it takes a long time for them to be noticed,” she says .

Now , the efforts may be working . During the first quarter , Delta had the second-lowest rate of complaints among the     52     10 carriers .    53     , its rate , along with other carriers’ , is up from last year . McCain and other lawmakers say there may be  a     54     to pass new consumer-protection      55    .
