Delta Airlines Customer Service Phone Number

I am working in Paris, and love to be here. This place contributes a lot in my life, Paris helped me to grow my lifestyle, my financial status, and helped me to enjoy the dynamic and unpredictable life. My family is living in Florida, I love my dad and wishing to reserve a dream trip to explore Paris. So, I dialed the Delta Airlines reservations number +1-855-805-5447 and asked the travel agent to secure three seats in the Business class cabin for my father, mother and my younger brother. Due to technical error, the travel experts recommend me to book tickets on the official website of Delta Airlines. I was unaware of the online booking process so I asked the agent to help me out.
