I don't think you can possibly lose a day between labs, regardless if your intercontinental flight is Gibraltar–Casablanca or Rio de Janeiro–Tokyo, because events are server-synced (to UTC) rather than device-synced (to its local time). That is, unless the airplane doesn't have wi-fi...

...but then you could take your time farming credits, if that's the problem with fully maxing the car. As to pro'ing it, I can't see any use for electric engines in the upcoming update, so I wouldn't worry about missing them (not this year, at least).
