United Drops Fares to Tokyo Below $600 Round Trip

United is selling round-trip economy fares to Tokyo Narita and Haneda from several US cities — including San Francisco, Los Angeles, and Chicago — for under $600. The same routes typically price between $900 and $1,200 round trip.

Which dates are actually available

The lowest fares are concentrated in September and early October, which is outside Japan's peak cherry blossom and summer tourist windows. That's part of why the price is this low — airlines cut fares on routes and dates where demand is softer. If you have flexibility to travel in fall rather than summer, this is a genuinely good window for both price and weather.

How to search for it

Fares like this don't always show up on the first search. Try searching one day at a time across a two-week window rather than using a flexible date calendar, since some fare tools don't display every fare class correctly in calendar view. Incognito browsing won't affect the price — that's a myth — but clearing stored cookies occasionally helps if a search tool is showing you a cached, outdated fare.

Fare class limitations

This fare is in United's most restrictive economy class, which means no free seat selection, a stricter change fee structure, and reduced mileage earning if you're a MileagePlus member. If you need to select a seat together with a companion, budget an extra $50 to $100 for seat assignment at booking.

Baggage

Basic economy on this route typically includes one personal item and a carry-on. Checked bags are extra unless you're using a co-branded United credit card that includes a free checked bag, which is worth checking before you pay separately at the airport.

Booking window

United has run this fare intermittently over the past two weeks, disappearing for a day or two and then returning. If you see it, it's reasonable to book rather than wait, since there's no guarantee it reappears on your exact preferred dates.
