Glossary
Definition: An airline route network model where most flights connect through a small number of major hub airports rather than flying point-to-point between every city pair. Used by virtually every major international carrier — enables high-frequency connectivity, premium-cabin viability, and economic efficiency.

Hub-and-spoke is the dominant network architecture for full-service international airlines. Instead of flying nonstop between every city pair (which would require many smaller, less-utilized aircraft), carriers concentrate flights through major hub airports where passengers from many origins can connect to many destinations.
Major US-international hubs: - **United**: SFO, EWR, IAH, ORD, IAD (5 major hubs serving Asia, Europe, Latin America) - **American**: DFW, MIA, JFK, LAX, ORD, PHL, CLT (7 hubs) - **Delta**: ATL, JFK, LAX, MSP, DTW, SEA, SLC, BOS (8 hubs)
Major international hubs: - **Star Alliance**: FRA (Lufthansa), MUC (Lufthansa), VIE (Austrian), ZRH (Swiss), IST (Turkish), HND/NRT (ANA), ICN (Asiana, but now under KE merger) - **Oneworld**: LHR (BA), MAD (Iberia), HEL (Finnair), DOH (Qatar), AMM (Royal Jordanian), SYD (Qantas), HKG (Cathay), HND/NRT (JAL) - **SkyTeam**: CDG (Air France), AMS (KLM), ATL/JFK/LAX (Delta), ICN (Korean Air), GRU (LATAM*)
Practical implications for premium-cabin booking: - **Hub access matters**: Living near a hub airport gives you more nonstop options and better pricing - **Connecting via the right hub** can dramatically reduce price (e.g. JFK-DOH-MEL on Qatar is often cheaper and better-product than JFK-LAX-MEL on US carriers) - **Hub airline lounge networks**: business class travelers benefit from the carrier's hub lounge facilities - **Banking patterns**: hubs operate departure/arrival "banks" (e.g. 8am bank, 11am bank, etc.) that determine when you can connect — flying outside the bank can mean a 3-hour layover instead of 90 minutes
Point-to-point carriers (Southwest, JetBlue's original model, several European LCCs) operate without traditional hub-and-spoke architecture — useful for short-haul leisure travel but less efficient for international premium connectivity.

A hub airport is a central airport used by an airline as a transfer point to funnel passengers from many origins to many destinations, creating efficient connecting itineraries through a single point.
IATA (International Air Transport Association) is the global trade association for airlines, representing approximately 300 airlines comprising 83% of total air traffic. IATA sets industry standards for ticketing, safety, and operations.
A herringbone configuration is a business class seat layout where seats are angled towards the cabin walls in a zigzag pattern, typically providing direct aisle access for every passenger in a 1-2-1 arrangement.
In-flight entertainment (IFE) is the onboard system providing movies, TV shows, music, games, and other media to passengers, typically via personal seatback screens in premium cabins with noise-cancelling headphones.
Global Entry is a US Customs and Border Protection trusted-traveler program that provides expedited clearance for pre-approved, low-risk international arrivals at US airports. Membership is $100 for 5 years and includes TSA PreCheck for domestic departures.
An interline agreement is an arrangement between two or more airlines to handle passengers travelling on itineraries that involve flights on multiple carriers, including through-checked baggage and coordinated rebooking during disruptions.
