Bottle Warmer on All Nippon Airways: The Complete 2026 Guide
ANA cabin crew prepare and warm formula on request on international flights — making a personal device optional. FAA lithium-battery rules still govern the device itself.
Yes — Per ANA's published policy, a personal bottle warmer is allowed in carry-on within standard cabin baggage limits, and ANA cabin crew prepare and warm bottles on request, which makes a device usually unnecessary on international flights.
The Exact ANA Policy
Word-for-word from the official source — no paraphrasing.
“Powdered milk is available on board... Our cabin crew will be happy to prepare it for you.”
How It Works on ANA
Every phase of your trip — written for this airline's specific process and terminology.
Before You Leave
Pack & prep — 24h ahead
Charge battery warmer to 100% the night before
Night beforeRecharging onboard is prohibited under 49 CFR 175.10. Charge fully at home so the device lasts the entire flight.
Decide whether you need a device at all
At packingANA's family page commits crew to preparing formula and hot water on request on international flights. If you skip the warmer, your carry-on is lighter and TSA screening is faster.
Label the watt-hour rating visibly on the warmer body
At packingTSA at JFK/LAX/SEA/IAD and ANA gate agents at HND/NRT both spot-check lithium devices. A visible '37 Wh' label (Baby Brezza) or '46 Wh' (Papablic) ends the question in under 10 seconds. Anything ≤100 Wh needs no airline approval per FAA PackSafe.
At Security
TSA checkpoint (US-origin) or JCAB (Japan-origin)
Declare formula and the battery-powered warmer at the start of screening
At checkpointTell the TSA officer you are carrying formula and/or breast milk and may have a battery-powered warmer. Request no-open (vapor/ETD) screening for liquids if preferred.
“I have baby formula and a battery-powered bottle warmer. The warmer is 37 watt-hours. Please use no-open screening on the bottles.”
Bottle warmer must travel in carry-on — never checked
At checkpointFAA hazmat rules forbid spare lithium batteries in checked bags. The warmer must remain in your carry-on.
At All Nippon Airways Gate
Boarding at HND, NRT, or US gateway
Use ANA's priority family boarding
At boardingANA offers priority boarding for families with children at HND and NRT. Widebody boarding is faster from the front of the line.
Confirm bassinet at the gate
Pre-boardingBassinets on all international aircraft except First Class and Dash 8, free, 10 kg limit, phone/LINE-app reservation 48h ahead. Confirm it is loaded.
“We requested a bassinet for seat [X] — can you confirm it's loaded?”
Onboard
Crew interaction for bottle warming
Ring the call button and request hot water for formula
After seatbelt sign offANA's published commitment makes crew bottle-warming a documented service, not a favor. Ring the call button after the seatbelt sign comes off.
“Could I have a cup of hot water to warm a formula bottle, please?”
Check which seats have AC/USB on your tail
After boardingIf using your own warmer, ask crew which seats have AC/USB on this tail — this varies by 777/787/A380 retrofit. Recharging in flight is technically prohibited (49 CFR 175.10) but powering a device that is already on is fine.
At Destination
Deplaning at HND, NRT, or US gateway
Plan to walk to baggage claim — no jet-bridge stroller return
On arrivalStrollers and car seats return at HND/NRT international baggage claim (oversized), not the jet bridge, on most ANA international flights.
File damage reports at the airport before leaving customs
At baggage claimFor damaged baggage, file with ANA baggage service at the airport before leaving customs. The Montreal Convention cap is 1,519 SDR (~$2,000–2,175) as of Dec 28, 2024.
Do You Need a Device? Pick Your Flight
ANA crew warm bottles on international routes — plan based on flight type and feeding needs.
Skip the device — ANA crew warm bottles on request. Pack two pre-mixed ready-to-feed (RTF) bottles for redundancy.
- Per CDC: use prepared formula within 2 hours, and within 1 hour once feeding starts
- Domestic Japan flights may stock fewer free diapers/formula than international widebodies
- No battery warmer needed when crew will warm on request
Bring one charged 37 Wh battery warmer as backup; rely on crew hot water otherwise.
- Bassinet eligible on international widebodies — request 48h ahead via phone or LINE app
- Formula and M/L diapers stocked on international flights per ana.co.jp
- ANA crew reliably warm bottles on these routes per RL12 Part B sentiment
Pre-charged battery warmer + 6+ RTF bottles + crew hot water = three-layer redundancy. Request bassinet (10 kg, 72 cm).
- Cabin crew bottle-warming is documented for international flights at ana.co.jp
- 777/787/A380 lavatories have changing tables per ana.co.jp
- Plan two feeds per six hours per CDC guidelines — RTF covers the first window
Federal Rules vs ANA's Rules
Where the airline aligns with TSA/FAA — and where it goes further.
What ANA Won't Put in Writing
Ask the galley before unpacking the warmer
On any ANA international widebody, ringing the call button and asking for hot water for formula is faster than digging the warmer out of an overhead bin. Crew prepare bottles per ana.co.jp's published policy — there's no need to apologize or explain.
Mark the Wh rating on the warmer body
TSA at JFK/LAX/SEA/IAD and ANA gate agents at HND/NRT both spot-check lithium devices. A visible '37 Wh' label (Baby Brezza) or '46 Wh' (Papablic) ends the question in under 10 seconds. Anything ≤100 Wh needs no airline approval per FAA PackSafe.
Reserve the bassinet 48h ahead via phone or LINE
Per RL5.md, ANA bassinets (10 kg limit) on all international aircraft except First and Dash 8 are reservable only by phone (1-800-235-9262, 24h) or via the LINE app — not the web booking flow. Walk-up requests at the gate fail most often.
Pack RTF formula for the first six hours
Ready-to-feed (sterile, room-temperature) bottles cover the highest-stress window — boarding through cruise. Use crew hot water and the warmer only after the seatbelt sign comes off. CDC: use prepared formula within 2h, 1h once feeding starts.
What To Do at the Gate If They Say No
ANA itself almost never refuses a bottle warmer — the published crew-warming policy makes refusal contradictory. The risk on this pair is TSA at the US-origin segment (JFK/LAX/SEA/IAD/BOS for HND/NRT flights) or JCAB security on the return.

Cite the federal anchor
At TSA, request the medically-necessary liquids exemption verbatim: TSA permits formula and breast milk in reasonable quantities; the bottle warmer is a battery-powered device under 100 Wh, allowed in carry-on per FAA PackSafe.

ANA + Bottle Warmer: FAQ
Does ANA warm baby bottles?
Yes — ANA cabin crew provide hot water and will prepare or warm formula on request, per ana.co.jp/en/jp/guide/reservation/support/international/family/. Verbatim: "Powdered milk is available on board... Our cabin crew will be happy to prepare it for you." This applies on any ANA international flight; on domestic Japan routes, free formula is less reliably stocked.
Can I bring a battery-powered bottle warmer on ANA?
Yes — a portable battery-powered warmer is allowed in carry-on per FAA PackSafe (≤100 Wh without airline approval). It must travel in carry-on, never checked, and cannot be recharged in flight under 49 CFR 175.10. ANA does not publish a separate device policy. Sources: faa.gov/hazmat/packsafe/lithium-batteries and ecfr.gov.
Does ANA provide formula and diapers on board?
Yes on international flights — powdered milk and M/L paper diapers are available, though quantities are limited; bring your own as backup. Domestic Japan routes stock less. Source: ana.co.jp/en/jp/guide/reservation/support/international/family/.
What size battery is allowed for a bottle warmer on an ANA flight?
Up to 100 Wh with no airline approval; 100–160 Wh requires airline approval; over 160 Wh is forbidden. Baby Brezza Bottle Warmer is 37 Wh and Papablic is 46 Wh — both ride freely without any paperwork. Source: faa.gov/hazmat/packsafe/lithium-batteries.
Can I bring breast milk on ANA without my baby present?
Per RL6 Japan row, ANA explicitly allows breast milk without the infant present when declared at the checkpoint — uncommon for Asian carriers (Singapore and Korea require the baby). Narita's checkpoint signage still presumes the baby is travelling, so declare and carry documentation. Source: research/RL6.md.
Can I use a USB-powered bottle warmer in my ANA seat?
Possibly — ANA international widebodies (777/787/A380) commonly have AC and USB at seat in Business and Premium Economy; Economy power varies by tail and retrofit. Recharging in flight is prohibited (49 CFR 175.10), but powering an already-on device is fine. Check Aerolopa or SeatGuru for your specific tail. Source: research/RL13_bottle_warmer.md Part B.
Does ANA charge a fee for a bottle warmer or infant feeding equipment?
No — personal feeding equipment falls within standard carry-on allowance; no surcharge applies. Lap-infant fares on international routes include a checked-baggage piece matching adult dims/weight. Source: ana.co.jp/en/jp/guide/boarding-procedures/baggage/international/child/.
What is the international liability cap if ANA damages a bottle warmer?
The Montreal Convention sets a cap of 1,519 SDR (~US$2,000–2,175) per passenger as of Dec 28, 2024, covering checked baggage on international itineraries. File with ANA baggage service at the airport before leaving customs. Source: icao.int/news/international-air-travel-liability-limits-set-increase-enhancing-customer-compensation-0.
