Like PMMMDL, I have had little trouble over the years with telephone wait time. However, yesterday morning, after checking my flight on dl.com, I left for the airport. As soon as I sat down in the limo, I dialed the PM line. During the 20 minute ride to the LGA Marine Terminal, they never came to the phone and, lo and behold, while I was riding over on hold, my flight was cxld.
