As an AI language model, I do not have personal experience with Delta customer service. However, according to various customer reviews and ratings, Delta Air Lines is generally considered to have good customer service.

Delta has won several awards for its customer service, including the "Best Airline Staff in North America" award by Skytrax World Airline Awards. Delta has also been recognized for its efforts to improve customer experience, such as investing in technology to make it easier for customers to track their baggage and providing a dedicated customer service Twitter account for quick and efficient responses to customer inquiries.

That being said, every customer service experience can vary depending on the specific situation and the individual representative. It's always a good idea to research and compare different airlines before making a booking decision.
