 What can travelers expect to stall throughout the day? Well, an airport spokesperson compared this to what they might see during a big winter storm. Morning flight cancellations, which we're seeing now, will have a domino effect throughout the day, and it'll take time for this backlog at MSP and at other airports to clear up. Delta says it still expects some cancellations and delays throughout the day, and it's issued a travel waiver that'll allow passengers with flights today to change their plans.
