dh and I are taking our 18mo dtds on a flight to Canada to see db. db can organise a buggy at his end but as we're visiting the Rockies, glaciers etc we want to mostly use out Littlelife carriers (leaving us hands free for dd1 - 4yo - and bags). The airline allows a pushchair per child but I'm wondering if anyone has been allowed to substitute for a carrier - I can only find people taking about the baby carriers like the Bjorns when I google and they'll be too big for those).
To me it makes sense and won't cause the airline extra hassle but the person dh spoke to seemed confused and said "no substitutions such as travel cots etc..." well it's not a travel cot it transports a baby like a buggy and takes the same space (if not less).
Trying to get head round the trip and really quite scared. Trying to make it as easy as possible with twins. Advice greatfully received.
