It is definitely not way more. It might even be less.
Some numbers I found: average Canadian car 206 gCO2/km.
Short-haul flight: ~150 gCO2/km/passenger
Car trip: ~200kg CO2 (1000km)
Flight: ~210kg CO2 (700km, 2 passengers)
Close enough that it depends on factors like what plane, what car, maybe even which way the wind's blowing.
If you're traveling solo, however, then it's better to fly unless your car is electric.
