About Regional Express
Rex Airlines Pty Ltd is an Australian regional airline based in Mascot, New South Wales. It operates scheduled regional services using turboprop aircraft.

Overview
Regional Express is an active scheduled passenger airline based in Australia. You will see it in booking systems as IATA ZL, and on the radio as "REX". OpenFlights tracks roughly 88 scheduled route pairs flown under its codes, reaching about 35 separate destinations.
Network and hubs
The network depends on three things: where the airline holds slots, the aircraft sitting in its fleet, and the bilateral agreements between Australia and the countries it serves. Like most carriers of its size, Regional Express operates from one or more home hubs, feeds nearby countries with regional flying, and stretches into longer thin routes wherever the demand and the aircraft line up.
Cabins and onboard product
What it feels like onboard depends on the part of the market the airline competes in. A short-haul, single-aisle fleet usually offers a flexible economy product and a front cabin that converts to business class on selected sectors. Longer-haul rotations, where they exist, add lie-flat business seats and sometimes a premium economy cabin in between. Catering, baggage rules, seat-selection charges and buy-on-board pricing all change with the route and the fare class, so the most reliable way to set expectations is to read the fare conditions at the moment you book.
Loyalty and partnerships
Frequent-flyer benefits depend on whether Regional Express belongs to a global alliance or runs bilateral partnerships with another carrier. Where alliance membership is in place, members of partner programmes can normally credit miles, get into lounges with eligible status, and through-check baggage on a single ticket. Even outside alliances, codeshare and interline agreements often let you build a simple combined itinerary on one record.
Operating notes
Operationally, Regional Express is registered in Australia and answers to that country's civil aviation authority. Onward flying follows the rules of every other country it serves. When you book, keep its IATA and ICAO codes handy for matching codeshare flight numbers, double-check terminal assignments at multi-terminal airports, and confirm any visa or transit rules that apply to the routing rather than only the marketing carrier on the ticket.
