Peach Narita-Incheon flights: schedule, terminals and bags

Peach began daily flights between Tokyo Narita and Seoul Incheon on September 20, 2026. MM651 leaves Narita in the morning, while MM652 returns from Incheon in the early afternoon. Peach uses Terminal 1 at both airports.

The route is useful for a short Japan-South Korea trip, but the lowest fare does not include a checked bag. Travelers also need to follow different airport check-in windows in each direction.

The practical answer: check that the booking shows NRT and ICN, then price the required bags before paying. At Narita, Peach's international counter is in the North Wing of Terminal 1. At Incheon, Peach also uses Terminal 1. Do not plan around a different terminal remembered from another airline or airport.

Peach's Narita-Incheon schedule

Peach's route page says the Narita-Incheon service started on September 20. Narita Airport's route announcement gives the daily timetable below.

Japan and South Korea use the same time zone, so there is no clock change to calculate. The timetable allows 70 minutes between the scheduled arrival of MM651 and the departure of MM652, but that is an aircraft rotation detail, not a connection promise for passengers.

Departure and arrival times can change. Search the exact date and flight number before committing to a train, hotel or separate onward ticket.

The route has started, but check the operating day

The flight has moved from announcement to operation. An independent launch report also recorded the first Narita departure on September 20. That does not make a months-old timetable the controlling record for a future trip.

Use Peach's flight status and the purchased itinerary on the day of travel. A low-cost route may be retimed, combined with a seasonal schedule update or affected by weather. The airline's published schedule currently changes season on October 25, so anyone traveling after that date should confirm the time loaded for the booking.

Narita Airport said Peach planned to use A320neo or A320ceo aircraft, with 188 or 180 seats. Treat that as planned equipment rather than a guarantee for a specific flight. An operational substitution can change the aircraft without changing the route.

Both flights use Terminal 1

Peach's Narita airport guide places international departures on the fourth floor of the North Wing in Terminal 1. Airport check-in and checked-bag acceptance run from 120 minutes until 50 minutes before scheduled departure.

Peach's Incheon guide places arrivals on the second floor and departures on the third floor of Terminal 1. At ICN, the carrier publishes a longer check-in window: 150 minutes until 50 minutes before departure. Counter locations can change, so use the airport screens after entering the terminal.

Peach says international passengers should be at the boarding gate 30 minutes before departure. The 50-minute check-in cutoff is a hard deadline, not a recommended arrival time. Allow extra time for transport, document checks, a bag queue, security and immigration.

Add baggage before comparing the final price

Peach sells Minimum, Standard and Standard Plus fares. Its current fare comparison lists checked baggage as a paid extra on Minimum. Standard and Standard Plus each include one checked bag.

All three fares include the same cabin allowance: one bag plus one personal item, with both items weighing no more than 7kg in total. Peach's carry-on rules say the three dimensions must add up to less than 115cm. Handles, pockets and wheels count, as do duty-free purchases made after security.

A regular checked piece can weigh up to 20kg. A bag over 20kg and up to 32kg needs an overweight option. Peach limits checked baggage to five pieces and 100kg per passenger, but fees vary by fare, route and where or when the bag is added.

For a weekend trip, compare the Standard total with a Minimum fare plus the required bag and seat. Save the final itinerary because the bundle name alone does not show what was actually purchased.

Give separate tickets a real buffer

Peach's new route can be one part of a longer trip through Narita or Incheon, but a same-day itinerary is not automatically protected. If the onward flight is on a separate booking, assume you may need to clear immigration, collect baggage, change floors or terminals, check in again and pass security unless the airlines confirm otherwise for that trip.

Do not use the 70-minute aircraft turnaround as a connection guide. Neither airport's process, the baggage belt nor border control is guaranteed to fit a tight self-transfer. A delay on the first ticket can also leave the traveler responsible for the second booking.

Where a same-day connection matters, compare the price of a through itinerary with the cost of a missed separate flight and an airport hotel. Check entry requirements for the passport involved, even if the planned time on the ground is short.

Plan the airport-city journey before landing

Narita is outside central Tokyo. The airport lists rail services and direct buses to Tokyo Station, Shinjuku, Shibuya, Ikebukuro and other districts. Choose by the final neighborhood, not by a generic claim that one option is always fastest. Check the operator's live departure time after immigration and baggage collection.

At Incheon Terminal 1, the Airport Railroad is reached from the basement transportation center. Express and all-stop services make different stops, so confirm whether the chosen train serves the destination. Airport buses and taxis are alternatives when luggage, a late disruption or the accommodation location makes rail inconvenient.

Save the hotel name and address in Japanese, Korean and English where possible. Also keep the first ground-transport option offline in case mobile service or a payment app takes longer than expected to work.

Check entry rules for the passport and trip

The new flight does not change Japanese or South Korean immigration rules. Entry permission, electronic authorization, visa requirements and arrival forms depend on nationality, residence, trip purpose and current government policy.

Check the relevant government service before buying a fare with limited refund options. The airline may verify documents at check-in, and an onward ticket or accommodation record can be easier to show when saved offline. A previous visa-free trip is not proof that the same rules apply now.

Keep data working on both sides of the flight

A travel eSIM can provide data after landing, but it does not provide onboard Wi-Fi, replace a voice line, satisfy entry requirements or guarantee that every app works in both countries.

The live Roaming eSIM catalog was checked on September 20. It listed 43 Japan eSIM plans, 33 South Korea eSIM plans and six Japan and South Korea eSIM plans covering both countries.

A country plan suits a traveler who needs data on only one side of the flight. A combined Japan and South Korea plan can reduce profile switching during a two-country trip, but allowance, validity, network, speed and top-up support depend on the selected package. Do not assume every plan can be topped up.

Some unlimited-labeled packages use a daily high-speed allowance, followed by reduced speed until the allowance refreshes. Read the live card before buying. Install while reliable internet is available, then follow the package's activation instructions so paid validity does not begin too early.

Before leaving for the airport, save these items offline:

• the MM651 or MM652 itinerary and booking reference;
• passport and required entry records;
• the fare name and baggage allowance;
• the Terminal 1 check-in location;
• the first train, bus or pickup plan; and
• the eSIM installation record and support route.

The guide to installing an eSIM before travel explains the difference between installation and activation. Check whether the phone supports eSIM before purchase if compatibility is uncertain.

Ten questions about Peach's Narita-Incheon route

1. When did Peach start Narita-Incheon flights?

Peach began the route on September 20, 2026. It is operating rather than only announced, but a future passenger should still check the purchased flight before travel.

2. Does Peach fly from Narita to Incheon every day?

The published schedule lists one flight in each direction daily. Times and operating dates can change, particularly when the seasonal timetable changes, so search the exact date.

3. What time is Peach flight MM651?

The launch timetable lists MM651 leaving Narita at 09:30 and arriving at Incheon at 12:25. Both are local times, and Japan and South Korea use the same time zone.

4. What time is Peach flight MM652?

The published schedule lists MM652 leaving Incheon at 13:35 and arriving at Narita at 16:15. Confirm the time on the current itinerary.

5. Which terminals does Peach use at Narita and Incheon?

Peach publishes Terminal 1 at both airports. Narita departures use the fourth-floor North Wing check-in area. Incheon departures use the third floor, with the specific counter shown on airport monitors.

6. How early can I check in for the Peach international flight?

At Narita, Peach publishes airport check-in from 120 to 50 minutes before departure. At Incheon, it publishes 150 to 50 minutes. International passengers should reach the gate at least 30 minutes before departure.

7. Is a checked bag included on Peach to Seoul?

It depends on the fare. Minimum charges separately for checked baggage. Standard and Standard Plus each include one checked bag under the current fare comparison. Check the booking before paying.

8. Does Peach really limit cabin baggage to 7kg?

Yes. One carry-on and one personal item are allowed, but the two items together must weigh no more than 7kg. The cabin bag's three dimensions must total less than 115cm.

9. Is a tight separate-ticket connection safe at Narita or Incheon?

No fixed buffer is safe for every traveler. Separate tickets may require immigration, baggage collection and another check-in. Allow for a delay and confirm terminal and entry requirements instead of relying on the scheduled arrival alone.

10. Can one eSIM work in Japan and South Korea?

Yes, if the selected plan's live coverage lists both countries. The combined catalog had six plans when checked on September 20. Package allowance, speed and top-up support still vary.

Booking checklist for MM651 or MM652

• Price required checked baggage before paying.
• Keep the two cabin items within 7kg combined.
• Reach airport check-in well before the 50-minute cutoff.

• Install and test the travel-data setup while reliable internet is available.

What we verified for NRT-ICN

Peach and Narita Airport provide the launch date, daily timetable, flight numbers, terminal guidance, check-in windows, fare inclusions and baggage limits. Incheon Airport and Narita Airport provide the ground-transport options. A same-day independent report was used to confirm that the route moved from announcement to operation.

Public traveler discussions were used to identify questions about terminal choice, luggage checks, counter opening, same-day trips and separate-ticket connections. They were not used as proof of airline or airport policy.

This page should be updated if Peach changes the timetable, frequency, terminal, fare structure, check-in process or baggage rules. Product availability and mobile-data terms should always be checked against the live card.
