My wife and I just got back from 10 days in Bonaire. You are right it is
quite easy to run up the 50lb limit. You have to be pretty careful
if you have a large bag. I don't think using 1 big bag for 2 divers
is going to work anymore.
We ended up traveling with 1 checked bag and 1 carryon
and 1 personal item (each) on the way out and 2 checked bags
and 1 item on the way back.
We didn't go with SCUBA specific bags because there are lots
of nice roller duffles out there for way less than the
scuba ones, Plus we wanted bags to use for non scuba trips
as well.
We avoid locks all together. Simply use zip ties. They
are cheap. Just make sure to carry your nail clippers in your pocket or carryon
bags to ensure you can get into your bags when you arrive.
TSA will cut the zip ties if they need to. If they cut them
they will replace them.
We used this for our carryons:
ebags.com Weekend Convertible
Its a great soft bag that can really be stuffed. No wheels but
it does have multiple handles and backpack straps. Its got lots of storage
and done quite nicely.
I used this for my main gear:
Samsonite Roller Duffle
This bag was great. The side pockets are large enough for my BIO fins.
The bag is quite large (more than enough room). I didn't have to worry about being super neat or cramming stuff in. and ran it up to 45lbs without the bag being completely full.
My wife used the Columbia Storm Chaser I (older version)
for her gear.
All of that being said I think the new rules are simply to get
and extra $25 out of travelers. The new rule is 50lb but you can
pay an extra $25 if you bag is between 50-70lb on most
flights (Check first). Just don't go over 70lb or it can get
real expensive.
After lugging all the bags, I think it might have been worth
it to pay the $25 just to keep the number of bags down.
I'll be interested in seeing if Airlines keep the 50lb rule
or go back to 70lbs or even 60lbs They might actually go back
to the higher weights because now that its 50lb, people will
end up taking 2 bags instead of 1 slightly heavier bag.
They will also probably stuff them full.
The net result may end up being twice as many bags
and more total weight than when the weight limit was
higher for a single bag.
