Guy Rettig, Class of 2026 hospitality business management major, spent his summer as a hospitality and planning intern for United Airlines.

Lerner: How did you find out about this internship? Why did you pursue it?

Rettig: I found out about this internship by looking online at areas of interest in the industry.

Lerner: What was the most exciting task or project that you completed?

Rettig: The main project I focused on was a project analyzing the international beverage provisioning, to create a more efficient inventory of beverages offered in-flight.

My favorite part of the internship was traveling to a Boeing facility for a future aircraft development meeting.

Lerner: What did you learn from the internship that you think you wouldn’t have learned elsewhere?

Rettig: Working with multiple teams to design ideal service procedures, and then compromising with what is possible given the weight and space restrictions on an aircraft.

Lerner: What is an example of a time where you were able to apply what you’ve learned at Lerner to your role?

Rettig: Utilizing a skill set built in-classes practicing presentations, I was able to create a professional capstone presentation to present to the entire commercial division of the company (450+ employees) which was also attended by the Chief Commercial Officer (CCO).

Lerner: Did you face any challenges during your internship? If so, what was the issue and how did you overcome it?

Rettig: For my project I was setting up a study to track beverage consumption on over 390+ individual flights. The catering operations team was unsure if the operation would be able to support this study. I had to pivot and change the scale, location, and time frame of this study, indulging in traveling to different airports to help conduct part of it myself.

Lerner: What are your career plans, and how do you think the internship will push you closer to your professional goals?

Rettig: In the future my goal is to pursue a career in corporate planning for food and beverage operations. This summer interning on the food and beverage team was a huge step forward, helping to reaffirm my interest in this field.
