where British Airways recently moved in with American Airlines. With just a carry-on, I headed straight to security. But there were plenty of kiosks and agents to assist with check-in had I needed it.

This means economy passengers flying on British Airways out of JFK will have a slew of kiosks to check in and plenty of queue space, while Finnair's little nook isn't as efficient or spacious.

British Airways was hit with a technical failure for ... of travelers using London’s Heathrow and Gatwick airports after check-in and flight start systems suffered a partial crash.
