which car seat for traveling? Boulevard or Symphony

[7costanza]

Family vacation on Monday! We will be on 3 flights over the next couple weeks and I'm wondering which car seat is best to take. It's my H and I with our 14 month old on Hawaiian Airlines, and we will also have two rental cars. He does have his own seat on the plane. We have a Britax Boulevard and Evenflo Symphony, which do you think is best for flying? He will be RF. I asked this on Car Seats for the Littles but no one responded, lol.

I have zero familiarity with the Symphony, but I do own a Boulevard. I am trying to find a carseat to take with us that's lighter than the boulevard. It seems way too bulky for travel IMO.
