LONDON (AP) — Delta Air Lines expects some 90 more flight cancellations globally before operations return to normal later in the day.

The airline has had to cancel over 1,700 flights since Monday, when a power outage at its base in Atlanta affected its global computer systems.

Dave Holtz, senior vice president for operations and customer center, says in a statement late Tuesday: "We will have a small number of cancellations in the morning as our operation restarts, so we continue to ask our customers to check their travel plans and flight status."

The company is predicting 90 flight cancellations for Wednesday, although tracking service FlightStats indicates there are about 150.

Delta canceled 775 flights Tuesday and 1,000 on Monday. Thousands more flights were delayed and passengers were stranded for hours, some overnight.
