How this guide was prepared
The ATC Practice Test Editorial Team compared Delta Air Lines’ current experienced-pilot hiring information and Propel Pilot Career Path material with the public PASS Delta preparation page on August 1, 2026. This independent guide separates employer-confirmed stages from a third-party commercial course description.
Delta does not operate one universal pilot entry route. An experienced First Officer applicant, a collegiate or CFI Propel candidate, a Delta employee using the Company Pilot Career Path, and a scholarship-path candidate may encounter different eligibility rules and selection events. Your vacancy notice, Delta candidate portal, assessment invitation, recruiter messages, and official preparation instructions always take priority.
PASS currently describes a Delta preparation package covering AON or Cut-E aptitude and reasoning practice, technical interview preparation, HR interview preparation, and simulator-oriented study. That list can help a candidate map possible preparation areas, but it is not an official permanent Delta specification.
Quick verdict
PASS may be useful for a Delta candidate who has confirmed the assessment provider and wants one environment for timed aptitude work, technical revision, behavioural interview preparation, and simulator-related study.
The main strength is breadth. The main risk is assuming that the same course plan applies to both Propel and direct experienced-pilot hiring. Delta’s official material describes a single-interview experience for Propel participants, while the experienced-pilot process currently includes an online assessment, panel interview, and final evaluations.
Recommendation: identify the exact Delta pathway first. Build a written checklist from the official vacancy and invitation. Use PASS only for modules that match that checklist, and supplement it with official company research, logbook and document preparation, evidence-based interview examples, and aircraft-specific technical revision where required.

Delta pathways are not interchangeable
Delta currently presents both experienced-pilot recruitment and several Propel pathways. Propel includes collegiate and CFI candidates, affiliate flight-school candidates, scholarship referrals, and eligible Delta employees. The programme is designed to provide a defined route through Endeavor Air toward the Delta flight deck when programme conditions are met.
Experienced pilots who already meet Delta First Officer requirements apply through the general pilot careers process. Their application and assessment journey should not be inferred from Propel marketing or collegiate programme explanations.
Before selecting preparation, record:
- the exact vacancy or Propel path;
- whether you are applying as an experienced pilot, CFI, student, scholarship referral, or employee;
- every assessment provider or module named in your invitation;
- whether the online assessment is confirmed;
- the interview format and location;
- whether any simulator event is explicitly included;
- the deadline and document requirements.
What Delta confirms publicly
For experienced pilots, Delta currently describes five broad stages: initial application, application review, interview process, pre-employment screenings, and indoctrination. Competitive candidates must pass an online assessment, a panel interview, and final evaluations before receiving a conditional job offer.
For Propel, Delta describes an integrated recruiting and selection approach with Endeavor Air and a single-interview experience. Eligibility and progression requirements differ by path. A successful Propel application does not remove the requirement to complete programme, qualification, performance, and professionalism conditions.
These official descriptions are more authoritative than any vendor module list. They still do not guarantee that every campaign uses identical assessment content.
What PASS currently describes
As reviewed on August 1, 2026, the PASS Delta page listed:
- Cut-E or AON aptitude and reasoning tests;
- technical test or interview preparation;
- HR interview preparation;
- simulator assessment preparation.
PASS also advertised ATPL revision, reasoning and mathematics tests, aviation English, personality material, Airbus A320 and Boeing 737-800 tests, forum access, content updates, and personal support.
Candidates should not infer that every extra is relevant. Aircraft-specific questions, simulator profiles, or aptitude providers can vary by pathway and campaign.
Preparation priorities
Application and documentation
Keep flight hours, certificates, medical information, passport or work authorization, employment history, and training records accurate and internally consistent. Review the application before submission because later corrections may be restricted. Prepare concise explanations for transitions, training events, checkride history, and employment gaps.
Online assessment
Use only the provider and instructions confirmed by Delta. If Aon/cut-e is named, practise the relevant timing, interface discipline, numerical or verbal reasoning, monitoring, and accuracy skills. If another provider is named, change resources. Avoid training only for speed: controlled accuracy and instruction compliance matter.
Panel and behavioural interview
Prepare examples covering safety, leadership, teamwork, conflict, decision-making, customer awareness, learning, accountability, and professionalism. Use real events and explain the situation, your actions, the operational reasoning, and what changed afterward.
Technical preparation
Revise the level of systems, performance, weather, regulations, aerodynamics, and operational knowledge appropriate to your licence and experience. Do not rely on memorized question banks as a substitute for understanding.
Simulator preparation
Only book targeted simulator preparation when a simulator event is confirmed. Focus on briefing discipline, raw-data control, stable scan, communication, workload management, threat and error management, and receptiveness to feedback rather than guessing an exact profile.
Common preparation mistakes
- preparing for Propel while applying as an experienced First Officer;
- assuming PASS’s AON label proves the live provider;
- memorizing behavioural scripts word for word;
- neglecting application consistency and flight-hour records;
- paying for simulator time before confirmation;
- treating a third-party forum report as official Delta policy;
- studying aircraft systems unrelated to the vacancy.
How to decide whether PASS is worth buying
A purchase is easier to justify when Delta has named an online assessment provider, the candidate has a short preparation window, and several PASS modules map directly to confirmed stages. It is harder to justify when the candidate is still waiting for an invitation, already has strong access to equivalent practice, or needs only interview coaching rather than a broad package.
Before paying, compare the access period with the assessment date, check whether the course contains the exact provider named by Delta, and decide whether aircraft-specific material matches the vacancy. A large library is not automatically better when only a small part is relevant.
Important limitations
Delta can change vacancies, eligibility rules, assessment providers, interview formats, hiring volumes, and programme conditions. PASS can change its course modules, access plans, prices, or support features. Neither source should be treated as a permanent specification.
No independent course can guarantee a score, conditional offer, Propel place, training completion, or job. Official Delta instructions control.
Final recommendation
PASS is most defensible when the candidate has a confirmed Delta assessment route and can select only the relevant modules. Experienced-pilot candidates should prioritize application accuracy, online assessment readiness, panel-interview evidence, and technical proficiency. Propel candidates should focus first on their programme eligibility, single-interview expectations, and long-term progression requirements.
Start with official Delta material, then use PASS Aon/cut-e preparation or the best pilot aptitude platforms comparison only when the match is clear.
