They could even do it with 120 minute ETOPS rules. See
http://www.chicago.com/cgi-bin/gc?PATH=PHL-NRT&ETOPS=120
Once you get past eastern Canada, where there are plenty of alternate
airports, the key alternates are as follows:
YZF Yellowknife, NT, CA
FAI Fairbanks, AK, US
PASY Shemya AFB, AK, US
UHPP Petropavlosk-Kamchatsky, RA
See
http://www.chicago.com/cgi-bin/gc?PATH=PHL-NRT&RANGE=120min@(YZF,FAI,PASY,UHPP,NRT)&RANGE-STYLE=outline
If Shemya is unavailable, PACD (Cold Bay, AK, US) can be substituted
with a minimal deviation from the great circle route. With 180 minute
ETOPS, this deviation is unnecessary, and there's considerable padding
to compensate for the strong northern winds.
