We are most likely flying from Indiana to Montana this summer. I am already fretting carseats. We have classic marathons or radian xtsl's that we could use. I have flown with the MA when my oldest was younger but always forward facing. The twins will be 2 yrs 4 months and my bet is still under 30 lbs. We will have a rental car when we get there. So....what is your favorite seat to fly with? Would you still rear face on the plane at this age/weight? I would consider getting a new cheaper seat just for this trip if it would make our life easier on the plane...one toddler per adult plus we have a will be 8 year old. I remember the pain forward facing the marathon and getting it unbuckled... Thanks!
