Very surprisingly Apia has two airports to its name, with the one at Fagali'i being by far the
more interesting of the two. It's effectively the domestic airport, with Polynesian Airlines' tiny
domestic fleet being based here, although in fact many of the flights are technically international
ones to nearby American Samoa. Although it's by no means busy, at least something happens
here (unlike at Apia-Faleolo!), with perhaps 8-10 movements on a good day. It's also far more
convenient than Faleolo, being only a few minutes drive east from the centre of Apia.
Although most of the airstrip seems to be surrounded by trees it should be possible to get
some reasonable shots from around the 'terminal' with care. You could try asking for airside
access but, ironically, the only time anyone is likely to be here to ask is when a flight is due,
and this will therefore be the least suitable time to allow unknown people airside.
It's also possible to get landing shots from the road that passes under the final approach to
Runway 10, but you'll need to have some idea of the schedules if you want to avoid sitting around
for a couple of hours waiting for something to happen.
