When in the days will they travel between NRT and HND?
Trains to connect the two airports are not in 24-hour operation.
The group discount by JR, which requires application in advance, is given concerning basic fares only, not also concerning additional charges on specific services such as Limited Express.
When a foreign visitor uses JR-East Limited Express service "Narita Express" from NRT to Tokyo Metropolis, a NfEX Tokyo Direct Ticket is cost-saving.
http://www.jreast.co.jp/e/pass/nex_oneway.html(No such JR discount ticket is now available regarding a way to NRT.)
Seats of "Narita Express" trains require reservation.
If they use JR lines first, they can easily change JR lines in Tokyo and Shimbashi Stations and then use Tokyo Monorail to the station in their HND terminal.
Tokyo Monorail has one station in each HND terminal:
Some non-JR trains are directly connecting NRT and HND, running on Keisei lines + Toei subway Asakusa Line + Keikyu lines. (These trains may be crowded depending on days, time zones and railroad sections.)
Seats of these NRT - HND direct trains are not to be reserved.
Keikyu has one station in HND International Terminal and one station for HND Domestic Terminals 1 and 2.
In November I am chaperoning 10 teenagers into Narita airport and on the train to Haneda. The teenagers will not have a chaperone on the return journey. How will the situation be?
You and they will take an international flight to NRT, you will accompany them until HND, they will take domestic flights from HND and back to HND and they will fly out from NRT; is that all right?
Have you confirmed that they cannot choose an international flight to HND or a domestic flight from NRT?
does each teenager have to produce a passport to buy one ticket On purchasing a regular railroad ticket, he/she does not have to produce his/her passport.
The above-mentioned NfEX Tokyo Direct Ticket is offered to a non-Japanese passport holder only, so when he/she purchases one, his/her passport should be confirmed.
Is Haneda airport well signposted in English so they can find the transit train to Narita? HND is serving international flights; signs in English language are found here and there in its two domestic and one international terminals.
Please note that Narita Station / Keisei Narita Station is
not the station for them to disembark at; these two stations are located outside NRT.
NRT has two terminals. JR-East / Keisei has one station in each NRT terminal. Trains bound for NRT make stops at Airport Terminal 2 Station then at Narita Airport Station (in NRT Terminal 1).
If the teenagers take different flights from NRT, their stations and terminals may be either different or the same.
