2015. Montes continued to draw praises and recognition from film critics for her role as Mia Generoso in Halik sa Hangin. In a review from Philippine Entertainment Portal, author Jocelyn Valle stated that "Julia, the actress, shows great commitment and earnestness in playing the character of Mia. She makes the viewer feel Mia's emotional stages of entering into the territory of romantic love — apprehension, excitement, caution, bliss — until reality bites. She shines the brightest in the pivotal scene where Mia is suspected to becoming a mental case, and Mia has to convince everybody that she's telling the truth."
