They had time to start brining in planes if that was their goal...
Nah, you'd need to properly take and surround the whole airfield and approaches. Not enough time for that, airplanes would be sitting ducks - especially if filled with troops.
They'd want it for that purpose to get troops on ground near capital in long term but short term they need a base in land for helos and armour to re-supply when it gets there. Without it the armour supply lines look very precarious behind them...
