Some said the Omicron variant can't stop people from going away for the holidays — and planning much-needed vacations for 2022. Travel-related stocks like cruises have led the subsequent market rebound as investors grow less fearful about the severity of the new variant.
However, reality doesn't seem to match the script. Since Friday, airlines scrubbed more than 1,500 U.S. flights, disrupting travel during the busy holiday weekend.  $United Airlines (UAL.US)$ ,  $Delta Air Lines (DAL.US)$ ,  $American Airlines (AAL.US)$  and  $JetBlue Airways (JBLU.US)$  cited the spread of omicron among crews as a reason for the cancellations. 
Do you think the virus will once again sabotage the travel demands?
