I am a traveler and recently visited the Delta Airlines ONT Terminal the staff provided clear information about flights and check-in, and they were courteous and helpful. The expeditious and effortless check-in procedure expedited my journey arrangements. The terminal had a pleasant vibe because it was tidy and well-organized. The airport’s well-lit signage and directions were another feature I enjoyed. All in all, I had a great experience, and I’m glad I decided to fly with Delta Airlines in the future!
