I think her physiology would keep her decently okay, she has a high constitution lending her a bit of an edge against the cold thus she might also continuously emanate her aura as she descends to meet the others, using her faith as her shield so to speak and that's where she can end up in your update as she reaches the Seekers just barely.

'Higher than average constitution' and a resistance to 'ailments' do not an immunity to crippling, lethal weather conditions make. If by 'ailments' you meant 'all status effects, including temperature' that warrants further investigation. As for timing, Laharl would have to throw his attention-catching tantrum after the other Seekers start to climb. Even if Flonne set out immediately, it would take her a long time to get over there. Maybe she could try flashing her healing field at Laharl to get his attention in return, and after a half hour or so they could meet one another halfway.

Edit: her field is also healing rather than any kind of shield, according to her sheet, so instead of protecting her from the cold at all it would only be able to heal the actual damage that the cold inflicts to her body, thereby slowing down the rate of her hypothermia.
