They could even do it with 120 minute ETOPS rules.  See

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


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.
