Transfer Narita to Haneda

We are arriving in Narita at about 2PM (14:00) on 30 March and need to transfer to Haneda for 5:40PM (17:40) departure. Is it feasible or should we look into a later flight? The flight at 5:40 PM is much cheaper than the later one, so our preference is to make it to the earlier one.

Is this on the same booking?

Different booking. The flight to Narita has been purchased already, but not the next flight. We are arriving on international flight and then going on a domestic flight.

As I picked up here, the recommended transfer time between airports is 3 hours.

If you have not booked for your domestic flight, check how much will be the additional if flying directly from NRT. Unless your flight is served via HND only, grab the flight direct from NRT if the additional is say less than 500 yen compared to flying from HND as the NRT to HND by limousine bus already costs 3000 yen.

Thank you. Unfortunately there is no flight from NRT. Given that a lot of flights are delayed recently, it sounds like it would be better to take a later flight in case there is a delay leaving from the origin.

@Sixties, is your destination not even served by LCC from NRT? Well then, aside from limousine bus, you may check the direct trains from NRT to HND via Keisei. Have a safe flight.
