What I actually look at when I review an airport

Airport rankings love waterfalls and wine lists. I care about something more boring: how predictably you can move a tired human from curb to pillow, or gate to noodles, without drama.

After sixteen years shuttling between SIN, LHR and JFK on the A380, my mental scorecard settled into eight questions. Most glossy lists only answer one or two. That is why frequent flyers roll their eyes at half the awards.

Last March, on a connection through Heathrow, I realised I could almost predict who wrote a ranking by what they praised. If they opened with shopping and architecture, I already knew they never transited with a tight minimum connection time.

Here is my framework, and then I will test it on one airport I am still undecided about, JFK.

---

1. Signage that works when you are half asleep

Good airports are legible without thinking. I watch for three things:

1. Consistency of iconography
2. Line of sight to the next decision point
3. How they treat edge cases like inter terminal transfers

FlyerTalk reviews of Changi’s Terminal 4 describe it as “idiot proof” once you are airside, you can see your gate and flight boards everywhere. Yet the same thread calls the shuttle signs to T2 and T3 tiny and badly placed. That split personality is exactly what I mark down.

At LHR, signage into central security is decent, but water fountains and quiet corners are practically hidden, as TripAdvisor regulars keep complaining. That tells me the airport was designed for commercial yield, not passenger orientation.

JFK is worst for this. r/travel and r/aviation users swap horror stories about inter terminal connections. One comment in late 2024 sums it up: land at T1, depart T7 at rush hour, and you can lose 45 to 60 minutes to AirTrain guesswork and elevator hunting. If signs punish non regulars, I cut points.

2. Time from aircraft door to landside or lounge

I do not care how pretty your terminal is if a simple arrival feels like a frontier crossing.

At SIN, over 130 automated lanes and more than 90% of eligible travelers using biometrics mean immigration often takes minutes. Most FlyerTalk reports talk about curb to gate in under 20 minutes outside holidays. When I was still working SIN LHR rotations, my “rest period” clock in my head barely started before we were through.

Compare that with Heathrow. UK parliamentary reports and Home Office data concede that one hour arrivals queues still happen during peaks, even with expanded e gates for about 40 nationalities. Live and Let’s Fly called T5 a sequence of queues, from 20 minute taxi in to more lines for security and buses. That is why experienced LHR regulars now pad non protected transfers to three hours.

So in my notes, I write:

• Plane to kerb under 30 minutes reliably: excellent
• 30 to 60 minutes, high variance: fragile
• Over 60 minutes at published peaks: broken

Most rankings ignore this and fixate on “wow” features. That is like reviewing Suites Class and only talking about the Krug.

3. Food quality under a realistic price ceiling

Airport food should be decent, findable, and not absurdly priced. My ceiling is simple:

• In Singapore, a satisfying meal airside under S$20
• In NYC, about 35 to 40 US dollars for a sit down meal with a drink, before tip, since Port Authority audits show this is still the JFK norm
• In London, around 20 to 25 pounds for something hot and honest

Skytrax and TripAdvisor reviews of SIN have started to puncture the “food paradise” myth. A January 2025 review complains that at 1 a.m. in T3, “almost everything decent to eat was shut” and 24 hour options were snacky or overpriced. I agree. Changi daytime dining is excellent, but late night value for money does not match the marketing.

At JFK, the “Street Pricing” policy supposedly capped airport markups at city levels, yet audits found vendors were previously charging up to 10 to 15 percent above benchmarks. Even after penalties, you still see 35 to 40 dollar meals as standard. For economy passengers that matters more than a fancy champagne bar they will never touch.

Most rankings treat any celebrity chef outlet as a win. I prefer to count how many places a family of four can sit, eat real food and not feel cheated.

4. Lounge density and crowding, not just decor

This is where my crew brain always kicks in. On a long rest period, you quickly learn that a quiet seat with power beats an Instagram wall.

Changi is “almost comical” in lounge density, as One Mile at a Time put it. Across four terminals there are over 15 airline and independent lounges, including at least four Priority Pass options in T1 alone. That gives you roughly 800 to 1,000 advertised seats for evening long haul banks, which is why regulars practise lounge hopping. They might shower at the SATS Premier Lounge (Terminal 1), then move closer to their gate for dinner.

Heathrow T4 is the opposite. As SkyTeam carriers ramped back up, more than half a dozen long hauls started leaving in a tight window from a terminal with only one major alliance lounge and a couple of independents. Capacity simply cannot absorb everyone, so lounge cards lose meaning.

JFK T4 is a masterclass in how not to fix this. After Delta’s renovations, flyers on FlyerTalk still report 20 to 35 minute lines just to enter the Sky Club between 4 and 8 p.m., followed by “seat hunting” for a plug. The physical space improved, access controls tightened, but peak loads remained.

When I review an airport, I calculate a basic ratio: widebody premium seats plus elites in the bank, divided by actual lounge chairs. If I know T8 has 29 contact gates and a single premium complex, I already expect the American Airlines Admirals Club Lounge (Terminal 8) to buckle at the transatlantic push.

5. Walking logic and connection friction

An airport can be big and still feel easy if the circulation is honest.

Changi’s refurbished T2 early check in is brilliant and flawed at once. You can drop bags up to 24 hours before departure for many airlines at a sleek landside zone. But transfer passengers coming from T3 by Skytrain now face an 8 to 10 minute walk at peaks. Regulars on r/travel already talk about budgeting for that in tight transits.

Heathrow is notorious for what I call “hidden friction.” A Live and Let’s Fly piece in 2024 noted T5 taxi in times approaching 20 minutes, then queues, then buses. Official minimum connection times may be legal, but an honest review should say: 90 minutes can feel tight, sometimes very tight.

At JFK, AirTrain has become a soft time penalty. Construction advisories in the Port Authority notes describe 10 to 20 minute delays layered on top of the nominal 6 to 8 minute run. r/aviation users now routinely warn that T1 to T7 at rush hour is a 45 to 60 minute project. Smart travelers respond by terminal optimizing, choosing itineraries that keep them inside T4 or T8, as various FlyerTalk trip reports describe.

Any ranking that treats “JFK” or “Heathrow” as a single experience without terminal nuance is misleading.

6. Power, quiet, and working ergonomics

I pay close attention to what you can do if you do not have lounge access. This is where many glossy “5 star” airports quietly fail.

Across all three of SIN, LHR and JFK, traveler reviews complain about scarce working outlets, noisy gate areas, and TV volume wars. Changi’s marketing shows serene work pods, but regulars on r/travel talk about hunting for laptop friendly tables away from announcements.

Heathrow T5 is a classic two tier experience. TripAdvisor reviewers say that if you have BA lounge access, it “is perfectly fine”, with showers and okay food. Outside, seating is cramped, power sockets rare and drinking water weirdly hidden behind pillars. That is not a five star pattern.

When an airport does something simple, like reasonably quiet seating near outlying gates with power at every second seat, I make a note. FlyerTalk users point out that the far end of JFK T8 is one of the few calm spots for work, which is not obvious from any official map.

7. Ground transport value for time

Last autumn, I did the mental math again on a late arrival in Manhattan. A taxi from JFK is now a 70 US dollar flat fare plus tolls and tip. Heathrow to central London can easily be 55 to 70 pounds. Changi’s taxis start at about S$4 to S$5, and a city run usually lands around S$20 to S$30.

So the usual “time from landing to hotel” question is also a money question. A 50 minute rail ride from Heathrow on the Piccadilly line is acceptable when the alternative is 70 pounds in a cab. From JFK, train calculus is knotted up with AirTrain disruption and transfer penalties. Port Authority advisories make it very clear that 10 to 20 minutes of padding is now normal.

Rankings almost never quantify this. They talk about “good public transport.” I write down real numbers.

---

8. How honest the marketing is

Finally, I ask: does the airport live up to its own myth?

Changi oversells late night dining and underplays that Jewel’s Rain Vortex is switched off from midnight to 6 a.m., while many Canopy Park attractions need paid tickets starting around S$8 to S$10 each. For a tired transit passenger at 2 a.m., that iconic waterfall is just a dark hole in a mall.

Heathrow publicises a security wait time tool with a 15 minute target, yet independent tracking shows 30 to 45 minute queues in T2 and T3 on Monday mornings. JFK talks about modernised terminals, and to be fair, T4 and T8 do look vastly better, but the inter terminal chaos remains.

I was wrong about this for years. I used to give airports credit simply for improvements, even if pain points stayed painful. Now I score them on how accurately they describe the experience an average passenger will have.

Applying the framework to JFK

So what do I make of JFK with this lens?

• Signage: weak, especially once you leave your original terminal. Too much dependence on local knowledge.
• Plane to kerb: highly variable by terminal. T4 and T8 have improved, but inter terminal connections are still described on r/travel as “third world”.
• Food: pricing now more controlled after Port Authority enforcement, but 35 to 40 US dollars per person at sit down spots is still painful.
• Lounges: T8’s refurbished premium complex and T4’s Sky Club look good in photos, yet real users report 20 to 35 minute entry queues and crowded seating. The Aer Lingus Lounge (Terminal 7) and older spaces are far more basic.
• Walking logic: AirTrain works as infrastructure, but during redevelopment it behaves like a random time tax.
• Power and quiet: pockets exist, particularly in outer T8, but they are not intuitive.
• Ground transport: 70 US dollar taxis to Manhattan and unpredictable train transfers are a tough combination.
• Honesty: the marketing has not caught up with the variability regulars document on FlyerTalk and r/aviation.

On my own internal scale, SIN sits at the top for functional reliability, despite its blind spots. LHR is a split personality: tolerable with status and careful planning, punishing without. JFK remains the airport I am most undecided about, because its renovated pieces, like T8 and future projects, are finally approaching what I would call competent design.

Wait, let me amend that. I am not undecided about JFK the experience, only JFK the trend line. The airport is moving in the right direction, but until the inter terminal chaos is solved and lounge crowding is treated as seriously as retail, no award or new concourse will change my basic verdict.

If you care about how an airport actually feels at 6 a.m. after a red eye, use these eight filters and ignore the waterfall photos.
