A Business Analyst at United Airlines plays a pivotal role in bridging the gap between complex data systems and real-world aviation operations. Operating in a highly dynamic industry where fuel costs, passenger demand, and scheduling constraints shift by the minute, you will be responsible for transforming raw data into strategic decisions. Whether you are placed in Digital Compliance, Network Planning, Finance, or Operations, your work directly impacts how the airline optimizes its fleet, enhances customer experience, and maintains regulatory standards.

The scale of operations at United Airlines means that your analytical models will influence millions of passengers and billions of dollars in revenue. You will work on optimizing flight routes, analyzing digital compliance across customer-facing platforms, and streamlining airport operations. This role is not just about writing queries; it is about understanding the operational pulse of a global airline and translating data insights into actionable business strategies.

To succeed in this role, you must possess a blend of rigorous technical capability and strong business acumen. You will collaborate closely with cross-functional teams, including engineers, product managers, and senior managing directors. The environment is fast-paced and intellectually challenging, requiring analysts who can navigate ambiguity and present clear, data-driven narratives to stakeholders at all levels of the organization.

The following questions are representative of what you can expect during the United Airlines hiring process. These questions are compiled from real candidate experiences and are grouped by category to help you identify key patterns in how the hiring team evaluates talent.

SQL & Technical Data Manipulation

These questions assess your ability to query databases, manipulate data, and write optimized code. Expect to write SQL queries on a whiteboard or paper during your technical rounds.

• Write a SQL query using window functions to find the top three busiest flight routes by passenger volume for each month.
• Explain the difference between an INNER JOIN and a LEFT JOIN, and write the pseudo-code for a complex join scenario on paper.

Preparing for an interview at United Airlines requires a balanced approach that covers technical fluency, logical structuring, and behavioral alignment. You should treat the preparation process as a simulation of the actual job: focus on clarity, efficiency, and business impact.

Role-Related Knowledge – You must demonstrate a strong command of SQL, Excel, and basic statistical concepts. Interviewers will look at how cleanly you write queries and whether you understand database efficiency.

Problem-Solving Ability – You will be tested on your ability to break down complex, ambiguous business problems. Whether it is a guesstimate or a business case study, your framework and structured approach matter more than the final numerical answer.

Leadership & Communication – Analysts at United Airlines do not work in silos. You must show that you can translate technical details into business recommendations and collaborate effectively with cross-functional teams.

Culture Fit & Core Values – The hiring team wants to see a genuine passion for aviation and a commitment to safety, customer service, and operational excellence. Researching recent airline trends and demonstrating a collaborative mindset will set you apart.

The interview process for a Business Analyst at United Airlines is designed to evaluate both your technical execution and your strategic thinking. The typical timeline spans between 3 to 6 weeks from the initial application to the final offer, depending on the location and specific team.

The journey begins with an initial HR screening call, which may be paired with an online questionnaire focusing on personality, logical reasoning, and situational judgment. Following this, you will transition into technical assessments, which often include a timed Excel test and a dedicated SQL coding round. The final stages involve deep-dives with hiring managers and senior leaders, focusing on business case studies, guesstimates, and behavioral alignment.

The visual timeline outlines the standard progression from your initial application through the technical hurdles and final executive evaluations. Candidates should use this timeline to pace their preparation, ensuring they master core technical skills before moving on to advanced case study frameworks and behavioral storytelling.

To excel in the United Airlines interview process, you must understand the specific competencies being evaluated in each core area. The following sections detail what the interviewers look for and how you can demonstrate mastery.

SQL & Data Manipulation

This is a critical technical gatekeeper for the Business Analyst role. You will face live coding challenges or paper-based pseudo-coding exercises designed to test your database fluency and query efficiency.

Be ready to go over:

• Window Functions – Mastery of ROW_NUMBER(), RANK(), DENSE_RANK(), and LEAD/LAG for analyzing sequential flight data.
• Aggregations & Joins – Complex multi-table joins, handling nulls, and filtering data using GROUP BY and HAVING clauses.
• Query Optimization – Understanding index usage, avoiding redundant subqueries, and writing clean, readable code.
• Advanced concepts (less common) – CTEs (Common Table Expressions), recursive queries, and basic database schema design.

Example scenarios:

• "Write a query to identify passengers who have booked more than three flights within a 30-day window."
• "Given a table of flight departures and arrivals, write a query to calculate the average turn-around time for each aircraft type."

Case Studies & Guesstimates

Interviewers use case studies and market sizing questions to evaluate your logical structure, business acumen, and comfort with mental math.

Be ready to go over:

• Structured Frameworks – Breaking down a business problem into mutually exclusive and collectively exhaustive (MECE) components.
• Operational Modeling – Understanding basic airline metrics like RPM (Revenue Passenger Miles), ASM (Available Seat Miles), and Load Factor.
• Estimation Techniques – Making reasonable, top-down or bottom-up assumptions to calculate market sizes or operational volumes.

Example scenarios:

• "How would you estimate the daily revenue generated by baggage fees at a major hub like Chicago O'Hare?"
• "A competitor launches a new route that overlaps with ours. What data would you analyze to decide whether we should match their pricing or adjust our flight capacity?"

Excel & Quantitative Analysis

Many business analyst teams at United Airlines require a timed Excel test. This test evaluates your speed, accuracy, and ability to build analytical models under time pressure.

Be ready to go over:

• Advanced Formulas – Expert-level use of XLOOKUP, INDEX/MATCH, SUMIFS, and nested logical statements.
• Data Visualization – Creating clean, professional charts and pivot tables that clearly communicate trends to stakeholders.
• Scenario Modeling – Using data tables, solver, or basic financial modeling techniques to evaluate business strategies.

Example scenarios:

• "You have 60 minutes to analyze a raw dataset of flight delays, identify the primary root causes, and build a dashboard summarizing your recommendations."
• "Create a dynamic model that projects fuel costs based on varying crude oil price scenarios."
