( CNN ) -- It may have taken a while , but travelers struggling to get home after Thanksgiving weekend will get to sleep in their own beds soon . After more than 4,000 U.S. flights were delayed and 244 were canceled Sunday -- one of the busiest travel days of the year -- airports should be much less chaotic Monday . As of early Monday morning , about 130 flights were delayed and 22 were canceled , according to FlightAware.com . Air travelers Monday probably wo n't see a repeat of the enormous lines like one at Chicago Midway International Airport . There , the line for security screening got so bad that reporter Denise Whitaker of CNN affiliate KOMO measured it : 1.2 miles . So what caused this ? `` This happens sometimes , '' Chicago Aviation Department spokeswoman Karen Pride said , according to CNN affiliate WLS . She said that between 6 a.m. and 8 a.m. Sunday , lines were long because `` that is when most people are traveling for the holiday period . '' But weather did n't play a big role at many major airports . Sure , snow snarled traffic for parts of the country on Wednesday , but conditions were much better Sunday in many areas . Chicago had temperatures in the upper 40s in Chicago . Denver , however , did get hit with bad weather . About 50 flights to Denver International Airport were diverted due to heavy fog , CNN affiliate KMGH reported . `` It 's going to take some time to catch up from this weather , '' airport spokeswoman Laura Coale told KMGH on Sunday . While a lot of attention goes to the airports -- where the interconnected flight travel system can have a domino effect -- the vast majority of Thanksgiving travelers hit the road . Ninety percent of travelers were expected to go by road , AAA predicted , helped by the lowest gas prices in five years . In all , more than 46 million people were expected to travel 50 miles or more for Thanksgiving , marking the highest volume since 2007 . `` The average distance traveled this Thanksgiving will be 549 miles roundtrip , and Americans will spend an average of $ 573 during the holiday weekend , '' AAA predicted .
