For me only if we figure out how to shorten airport time. Otherwise train in europe is easier - and usually located directly downtown or close instead of an hour in a car with traffic.
Small aircraft can operate from regional airport which are much, much faster to board and disembark from then the large airports that behemoths have to use. I really don’t understand all the hate for a smaller electric aircraft. There are tons of advantages, and the difference in pilot labor costs are practically trivial. (I think a big driver for larger aircraft had been reducing number of engines per passenger as jet engines are expensive to maintain and the larger ones are also more efficient, but this isn’t really applicable to electric motors.)
If? Spain has security checks on major train stations which makes it slower than in other countries but still way faster than airports. Trains have way more doors for example and it is easier to get a timeslot to leave than it is to get one to taxi.
