What is the smallest aircraft you have flown on for an international flight?

What is the smallest aircraft you have flown on for an international flight?

I flew on an Air BC Dhc6 twin otter from Victoria Canada to Seattle USA in March 1986. Only had 15 seats! Check in staff couldn't stop laughing when I checked in 2 hours prior to dep time!!!!

I have flown an an American Eagle (AA) Bombardier CRJ-700 between JFK and Toronto. I think there were only around 60 seats on board. Great little aeroplane but terrible American Airlines service...

Cannot agree more about "terrible American Airlines service"

I have flown the Q300 from Seattle to Vancouver. Bumpy ride in bad weather!

I know of a few people who flew a handful CT4s from NZ to AUS. Additional bladder fuel tanks inside the cockpit. Not a flight I would enjoy. 

ATR42-500 operated by Flybe (Nordic) from Helsinki to St Petersburg.

Boarded by bus and everyone had their visa checked upon boarding the bus and plane.

A 19 seat Dash 6 from San Jose Costa Rica to Managua Nicaragua on Nature air. 

Back in the early 2000's - ATR42-300 Eindhoven (EIN) -London  (LHR). Had a 30 minute hold over London and felt very small as a 747 went by.

Avro RJ100 from Prague to Geneva on Swiss.

SAAB 340 Düsseldorf to London City. 

Porter Q400 from Toronto City Airport (one of the best located airports in the world) to Newark.

Thai International Caravelle in 1969 HKG (Kai Tak)-TPE-SEL (now GMP). At 72 seats it was not small by the Dash 6 yardstick,  but a classic early jet nonetheless.

Nice post.

Air Canada Dash 8-300, Toronto to BWI. Close second and shortest Int flight, Finnair (op by Flybe) ATR72, HEL-TLL 

Beech 1900D operated by PGA Express from Casablanca to Lisbon... that journey across the ocean was nerve racking but the complimentary noiseplugs were well appreciated.

No cabin crew, sandwhich and water in a box on our seats and 2 pilots who came  out and were all like "everyone buckled up?"

Nothing as small as the above...bmibaby 737-500 between London and Cork.
