Walk me through your background + your path into airline network planning.

What it tests: Story arc - quantitative training + aviation / network exposure + a concrete planning anchor. Interviewers screen for deliberate path, not 'I like planes'.

Tell me about a route, schedule, or fleet decision you've owned end-to-end.

What it tests: Modeling rigor + commercial + schedule lens. Can the candidate walk problem framing -> demand + share -> economics -> recommendation -> commercial sign-off cleanly.

Why airline network planning vs shipper / consulting / pure RM?

What it tests: Authentic alignment - strategic + commercial pace, multi-year horizon, network-level pattern recognition vs single-flight RM or pure analysis.

Why this carrier type - legacy hub / low-cost / ULCC / long-haul JV?

What it tests: Specificity. Generic 'I like airlines' fails. Each carrier type has distinct network economics.

What it tests: Real homework - hub + fleet + alliance + recent moves - not 'great brand'.

What's your read on our network + hub structure + recent moves?

What it tests: Industry literacy - hub structure, fleet mix, route portfolio, recent launches / cuts, competitive position.

Tell me what you understand about our alliance + JV + slot posture.

What it tests: Commercial + regulatory maturity - JV partners, metal-neutral economics, ATI + bilateral footprint, slot portfolio at constrained airports.

Walk me through how you'd evaluate launching a new route.

What it tests: Quantitative + commercial fluency - O&D framing, share modeling, economics, competitor response, strategic fit.

Network Planning interview prep.

Trained on route planner / schedule planner / fleet assignment analyst / slot strategist / network strategy interviews across legacy hub carriers, low-cost point-to-point operators, regionals, ULCCs, and long-haul JV / alliance carriers.

What interviewers look for

Can the candidate frame a route launch - O&D demand, share model, profitability, strategic fit?
Do they understand hub economics - connectivity, banking, MCT, gauge, stage-length cost curves?
Are they fluent in fleet assignment - aircraft economics, swap rules, tail-routing constraints?
Can they navigate slot strategy at constrained airports - IATA Worldwide Slot Guidelines, use-it-or-lose-it?
Do they understand codeshare + JV + alliance economics - metal-neutral revenue share, antitrust immunity?
Are they grounded in bilateral + open-skies access + foreign-ownership constraints?
Can they read competitive response - share defense, capacity discipline, fare matching?
Long-game fit - analyst / senior / manager / director / VP network strategy trajectory?

Technical concepts to master

Network design fundamentals - hub vs P2P + connectivity

Hub-and-spoke vs point-to-point: Hub-and-spoke = traffic gathered + redistributed at hub bank; point-to-point = direct city-pair service without connecting traffic engineered.
Banking + connectivity: Hub bank = cluster of arrivals + departures within MCT window enabling connections; bank quality measured by connections within MCT weighted by O&D demand.
MCT (Minimum Connect Time): Minimum minutes required between connecting flights at a hub - varies by airport, terminal, domestic / international, security regime.
Gauge vs frequency trade-off: Carrying the same ASMs via larger gauge (fewer departures, more seats) or higher frequency (more departures, smaller seats); frequency wins share via S-curve.

Fleet assignment + tail routing

Fleet Assignment Model (FAM): MILP optimization assigning aircraft types to scheduled flights maximizing contribution subject to count + maintenance + crew + station constraints.
Tail routing + utilization: Sequencing individual aircraft tails through a schedule - daily / weekly rotation, overnight bases, maintenance returns.
Family commonality: Operating closely-related types (e.g. 737 family, A320 family, A330 / A350 cross-crew credit) yields crew + maintenance + spares efficiency.
Swap economics + fleet flexibility: Mid-schedule swap = substituting one type for another on a flight; constrained by gate compat, runway perf, crew quals.

Alliance + JV + codeshare economics

Global alliances: Star (UA / LH / SQ / NH / etc.), oneworld (AA / BA / QF / JL / etc.), SkyTeam (DL / AF-KL / KE / etc.) - frequent flyer, lounges, codeshare, schedule alignment.
Joint Venture (JV) + metal-neutral: JV partners share revenue across joint flights regardless of who operates - 'metal-neutral'; antitrust immunity required.
Antitrust immunity (ATI): DOT / EU competition authority grant allowing JV partners to coordinate on price, capacity, schedule - what makes metal-neutral JVs possible.
Codeshare types: Free-flow (codeshare without revenue agreement), block-space (partner buys block of seats), and JV-level revenue sharing.

Share + demand models - QSI + S-curve + data sources

QSI (Quality of Service Index): Score per itinerary capturing frequency, elapsed time, equipment, codeshare, brand - sum of carrier QSI / total QSI gives market share.
S-curve: Empirical observation that market share rises non-linearly with frequency share - >50% frequency typically yields >50% share, 'frequency premium'.
MIDT (Marketing Information Data Tapes): GDS-derived booking data across travel agencies + corporate channels - O&D + carrier visibility, but excludes direct (carrier.com).
DDS (Demand Data Service) / DB1B: DDS = IATA carrier-share dataset; DB1B = US DOT 10% ticket sample (Origin + Destination Survey) - canonical US carrier-share + fare reference.

Practical drills

A competitor flies 2x daily on a 2000-mile O&D market with 180-seat narrowbody. Total O&D demand is 600 passengers per day each way; competitor captures ~60% (~360/day) at avg fare $250 one-way. You're considering launching 2x daily, 180 seats. Walk through your share + revenue + profitability estimate. Assume CASM at 2000 mi is 10 cents.
A medium hub has 6 banks per day; gate + ramp peak utilization is binding at 95%, causing taxi delays + misconnects. Options: (A) de-bank to a continuous schedule reducing peaks; (B) re-bank to 5 stronger banks; (C) hold + add gates ($150M capex). How would you frame the analysis + what's your initial recommendation?
A ULCC announces 4x daily new service on one of your top 10 hub-to-hub trunk routes, where you currently fly 6x daily with 160-seat gauge at avg $220 fare. They'll fly 200-seat gauge at $99 base. Walk through how you'd analyze + recommend a response.
