Delta Airlines is known for its reliable service. That's why many people book their travel through Delta Airlines. However, in the past few weeks, Delta Airlines has been experiencing some technical difficulties with their booking system. As a result, many customers have had trouble rebooking flights or getting help with anything related to their reservations. In light of this problem, it might be a good idea to double-check your airline ticket before you go to buy it so that you aren't left stranded if something goes wrong.
