Peach Aviation Daily Narita Incheon Planning From Sept. 20

Peach Aviation started daily flights between Tokyo Narita and Seoul Incheon on Sept. 20, 2026, its first new international route from Narita in seven years.

The airline’s Narita to Seoul page lists one round trip: MM651 leaves Narita at 9:30 a.m. and reaches Incheon at 12:25 p.m., and MM652 leaves Incheon at 1:35 p.m. and reaches Narita at 4:15 p.m. Japan and South Korea share the same clock, so those are the local times on both ends.

If you are booking Tokyo to Seoul through Oct. 24, this is the new Narita option beside Peach’s existing Haneda flights. Airline guides on Deep Arrival’s airline pages are the place to compare carriers before you lock a ticket. Narita’s trains are a separate problem this week, covered in the Typhoon No. 25 rail note. A Peach ticket does not restore the suspended JR lines.

One Daily Round Trip From Narita

Peach’s Sept. 20 release says the route runs seven days a week as one round trip a day. That is the whole Narita pattern: morning out, early afternoon back. The English route page repeats the same four times and marks the flights daily.

The page still carries a line that the schedule is subject to approval by the relevant authorities. The launch release is past that hurdle for the first flight, which already left. Treat the asterisk as a reason to recheck times before you pay, not as a sign the route is still a proposal.

The First Narita Departure Left at 9:38 a.m.

Peach’s Sept. 20 release says MM651, the first Narita departure, pushed back at 9:38 a.m. with 188 passengers, including one infant. The posted timetable says 9:30 a.m. The eight minute gap is that morning’s departure, not a new schedule.

The same release sets the operating window at Sept. 20 through Oct. 24, 2026. It describes the return as a 1:35 p.m. departure from Incheon and a 4:15 p.m. arrival in Japan, which matches MM652 on the route page. Peach also said this is the first new Narita international route since 2019.

Haneda Is Still the Other Seoul Door

The Narita page also lists a daily Haneda pair. MM809 leaves Haneda at 2:10 a.m. and arrives in Incheon at 4:40 a.m. MM808 leaves Incheon at 10:35 p.m. and arrives at Haneda at 12:55 a.m. Peach’s own example is to leave Narita in the morning and come home via Haneda late, which it says can stretch a Seoul stay.

Those Haneda times are on the same page as the new route, with the same approval note. They are not a second Narita flight. If your ticket says Haneda, the Narita 9:30 a.m. departure does not apply.

Bags and Seats Are Extra

The launch release says checked bags and seat assignment cost extra, and that the fast area cannot be assigned as a seat. Booking through the contact center or an airport counter adds a reservation fee. The release does not print those amounts, so the checkout page is the price, not this article.

Peach also said in that release that Korean routes are the first to get hot inflight meals. It did not put a menu or a price in the launch note. Narita rail is the other check: the posted Peach times assume you can reach the airport, and several Chiba lines are still recovering from Typhoon No. 25.
