Staff Travel & ID90 Tickets Explained
How standby staff travel actually works: ID90 and ID50 fares, ZED agreements, buddy passes, loading order — and the etiquette rules that keep the benefit alive.

The golden rule: you fly if there's space
Almost all staff travel is standby, formally "space available" or SA travel. You pay a heavily reduced fare (sometimes just taxes), you list for a flight, and you board only if seats remain after every paying passenger — including last-minute rebookings — has one. On a quiet Tuesday you'll sit in row 8 wondering why anyone pays full fare. On the Friday before a school holiday you can spend three days at an airport watching flight after flight close in your face.
The craft of staff travel is load-checking: staff portals show booked figures against capacity, and experienced non-revs (non-revenue passengers) never fly without a plan B and C — an alternate routing, a nearby airport, or a refundable commercial fallback for the flight they truly cannot miss. The universal veteran rule: never non-rev to something with a fixed start time (a cruise, a wedding, your own assessment day) without at least a full day's buffer.
The fare alphabet: ID90, ID50, ZED and more
The codes you'll hear in crew rooms, decoded:
- ID90 — an industry discount ticket at 90% off the full published fare, on your own or another airline; historically the classic interline staff fare, usually standby
- ID50 — the 50%-off version, often confirmed (a real reserved seat) rather than standby, useful when you must arrive
- ZED (Zonal Employee Discount) — the modern multilateral system most airlines use for travel on OTHER carriers: flat fares by distance zone in three levels (ZED Low/Medium/High), plus taxes; over 170 airlines participate
- ZED-M vs ZED-F — many agreements offer a cheaper standby fare and a pricier confirmed option between the same city pair
- Duty travel / firm tickets — positioning tickets for work are confirmed and are a different thing entirely from leisure standby
- Yield fares / own-airline staff fares — each airline's internal system for its own network, often just taxes and fees for the employee
Interline agreements and who boards first
Your airline's staff travel network is only as good as its agreements. Bilateral interline and ZED agreements decide which other carriers you can list on, in which cabin, and at what fare level — a well-connected flag carrier's staff travel reach covers most of the planet, while a small low-cost carrier's may cover only its own network. Check the agreement list before assuming you can "just ID90" somewhere exotic.
When more standbys are listed than seats exist, loading order (boarding priority) decides. The typical hierarchy: own-airline employees on leisure travel rank by category and often by seniority or listing time; retirees and parent-company staff follow; other airlines' staff on ZED/interline fares rank below the home airline's people; and buddy pass riders board last of all. Your priority code matters more than your fare — a cheap own-airline listing frequently outranks an expensive interline one.
Buddy passes: a gift that can burn you
Most airlines grant employees a set of buddy passes — discounted standby tickets for people outside the immediate registered family. Two facts your friends must understand before you hand one over: they board in the lowest priority group, so peak-period travel can genuinely strand them for days; and their behavior is charged to your file. A buddy pass rider who argues with a gate agent, dresses inappropriately, or tries to jump the standby queue can cost you your entire staff travel benefit or your job.
Give buddy passes only to people you'd trust to represent you at your own workplace, brief them in writing on dress code and conduct, and never, ever sell them — selling staff travel is a termination offense at essentially every airline and audits do happen.
Etiquette: the unwritten rules that protect the benefit
Staff travel is a privilege airlines can withdraw, and non-rev behavior is watched. The code:
- Dress smart-casual minimum, whatever the written policy now allows — gate agents exercise discretion and remember faces
- Never ask crew or gate staff for upgrades, seat changes or favors; accept what you're given with visible gratitude
- Do not mention your airline, discount or standby status to seated paying passengers
- If service is short or seats are tight, you volunteer to be the flexible one — including taking the middle seat without a word
- Never post real-time complaints about your standby experience with the airline tagged; social media has ended staff travel privileges
- Thank the gate agent by name when they board you — they had discretion, and next month you'll need it again

Frequently asked questions
What does ID90 mean on a plane ticket?
ID90 is an industry discount fare: 90% off the full published fare, available to airline staff (and sometimes eligible family) usually on a standby basis. ID50 is the 50%-off, often confirmed-seat version. Many airlines have now replaced bilateral ID fares with the multilateral ZED fare system.
Can flight attendants' families fly free?
Registered immediate family (spouse/partner, dependent children, often parents) typically get the same or slightly lower standby privileges as the employee, paying only taxes and fees on the home airline. Friends use limited buddy passes at lower priority. Nothing is guaranteed a seat — it is all space-available.
How do ZED fares work between airlines?
ZED (Zonal Employee Discount) is a multilateral agreement covering 170+ airlines. Fares are flat rates based on flight distance zones, not the commercial price, set at Low/Medium/High levels per agreement, plus taxes. Most ZED travel is standby, though some agreements sell confirmed versions.
