Infant travelling: Premium Economy or Economy Preferred Seat

Hi there,

My wife and I along with our infant (10month old) are looking at booking a long haul flight from Vancouver to Manila (787 Aircraft) and are considering choosing either Premium Economy or Economy with Preferred Seating.

We are leaning towards Preferred seating in Economy as our understanding is that we would be eligible for a bassinet. However, would it be worth the damage to the wallet by upgrading to Premium Economy considering all the perks we would get compared to Economy? It's about a $1,200 (CAD) difference (per Adult) between the two.

Thanks in advance!
