The short answer: for most airline jobs you need conversational English at around CEFR B1–B2. Cabin crew are typically expected to hold a conversation comfortably at B1–B2, and that ability is tested live at the interview rather than by certificate. Pilots and air traffic controllers who fly internationally must hold ICAO Operational Level 4 or above — a formal licensing requirement. Ground staff and customer service roles usually sit around B1, with stronger English expected the more passenger-facing the role. Every airline sets its own bar, so treat these as the industry-wide pattern — and always check the specific job listing before you apply.
Below: the role-by-role picture, how each level is actually assessed, and how long the gap typically takes to close.
The expectations, role by role
Airlines rarely publish a precise CEFR score in their job adverts. What they describe instead — “fluent English”, “good command of spoken and written English”, “able to communicate confidently” — maps quite consistently onto the levels below across the international industry:
| Role | Typical English expectation | How it’s usually assessed |
|---|---|---|
| Cabin crew | Conversational B1–B2 | Live, at the recruitment day: group tasks, role plays and a one-to-one interview; some airlines add an online English test |
| Pilots | ICAO Operational Level 4 or above (a licensing requirement for international operations) | A formal ICAO language proficiency test, with periodic re-testing at Level 4 and 5 |
| Air traffic controllers | ICAO Operational Level 4 or above | Same formal ICAO test regime as pilots |
| Ground staff & passenger services | Typically B1 | A conversational check at interview; written English matters for roles that handle documentation |
| Customer service & call centres | B1–B2, depending on the market served | Interview plus, in some cases, a short written or listening test |
Two honest caveats. First, these are patterns, not rules: a carrier hiring for domestic routes may ask for less, and a long-haul international airline may in practice expect more than its advert states. Second, an interviewer doesn’t care which level a certificate says you are — they care whether you understood their question the first time and answered naturally.
Cabin crew: the interview is the test
For cabin crew, English is assessed the hard way: live. Recruitment days are typically run entirely in English — the ice-breaker, the group exercise, the role play, the final interview. Recruiters are listening for whether you can follow rapid, natural speech, respond without long pauses, and stay polite and clear when the scenario turns awkward: a nervous passenger, a service complaint, a safety instruction that must land first time.
That has a practical consequence for how you prepare. Memorised answers and grammar drills help less than sustained speaking practice, because hesitation is the thing assessors notice most. We’ve written a full guide to how airlines test cabin crew English at interview — what the stages look like and how to practise for each one.
Pilots and controllers: ICAO Level 4 is the law, not a preference
For flight crew and air traffic controllers the situation is different in kind, not just degree. The International Civil Aviation Organization requires pilots and controllers operating internationally to demonstrate English proficiency at Operational Level 4 or above, assessed across six areas: pronunciation, structure, vocabulary, fluency, comprehension and interaction. Your overall level is your lowest score of the six, and Level 4 and 5 holders must re-test periodically to keep the endorsement on their licence.
In rough CEFR terms, ICAO Level 4 sits in the region of B1–B2 — but the comparison only goes so far, because the ICAO test measures plain aviation English: describing an unexpected situation on the radio, clarifying an ambiguous instruction, communicating when standard phraseology runs out. Strong general English alone can still be caught out by its listening material and emphasis on spontaneous speech. Our guide to preparing for the ICAO English test covers the six rating areas in detail, and our full Aviation English guide maps the wider landscape — radio calls, phraseology, and the language of every aviation role.
Step one: find out where you are now
Everything above only becomes useful once you know your current level — and most people guess theirs wrongly, in both directions. Take our free online English level test: five minutes, no sign-up, and an instant CEFR result from A1 to C2. That result turns a vague ambition (“get good enough for an airline”) into a measurable gap (“I’m A2+, I need B2”).
How long does it take to close the gap?
Honest ranges, because intensity, starting point and language background all matter: moving up one full CEFR level typically takes somewhere between 100 and 300 hours of combined lessons and self-study. The steps get longer as you climb — A2 to B1 usually sits at the lower end of that range, while B1 to B2 commonly needs 200 hours or more, because “intermediate to upper-intermediate” is where vocabulary breadth and listening speed really start to count.
In calendar terms, a learner studying consistently — a few live classes a week plus regular self-study — can realistically expect a single CEFR step to take several months, and a two-step jump (say A2 to B2) to take a year or more. Cramming rarely shortens this much; consistency does. We break the numbers down properly in how many hours it takes to move up a CEFR level.
The encouraging flip side: if you test at B1 and your target role expects B1–B2, you are one focused step away — and targeted aviation-specific practice (interview scenarios, service language, radio-style listening) closes that kind of gap faster than general study alone.
The bottom line
You don’t need perfect English to work for an airline. You need reliable, conversational English at roughly B1–B2 for most roles, or ICAO Level 4 if you’ll be on the radio — and it has to hold up under the mild pressure of an interview or a test, not just on paper. Find out your level, measure the gap honestly, and give it the months it genuinely takes. For structured help, our FLY ME! Aviation English programme was built for exactly this: live online classes that train the English of the aviation workplace, from interview day onwards.
Frequently asked questions
What level of English do you need to be cabin crew?
Most international airlines expect conversational English at around CEFR B1–B2 for cabin crew. Crucially, it is almost always assessed live at the recruitment day — through group exercises, role plays and a one-to-one interview — rather than by a certificate. You need to understand quick questions, respond naturally, and handle service and safety language under a little pressure. Each airline sets its own bar, so always check the specific job listing.
What English level do pilots need?
Pilots and air traffic controllers who operate internationally must hold at least ICAO Operational Level 4 English, a licensing requirement set by the International Civil Aviation Organization. It is assessed in a formal test covering pronunciation, structure, vocabulary, fluency, comprehension and interaction, and Level 4 holders are re-tested periodically. Roughly speaking, ICAO Level 4 sits in the region of CEFR B1–B2, but the test focuses on plain aviation English, not general academic English.
How long does it take to reach the English level airlines ask for?
It depends on the size of the gap. Moving up one full CEFR level typically takes somewhere in the range of 100–300 hours of combined lessons and self-study, and higher steps take longer than lower ones — B1 to B2 usually needs more time than A2 to B1. A learner at solid A2 aiming for B2 should realistically plan for several months to a year of consistent study. The sensible first step is a free level test, so you know exactly how far you have to go.
