Planning a long haul trip with toddler DS (will be 18m at the time) and have some air miles to use - which has given us the option of either 2 bussiness class seats or 3 economy seats. Have only ever flown economy before, and up to now had DS on our lap. Now not sure whether the extra space with 3 seats (though not sure of that would mean we need to bring a car seat for him) or the 'lie flat' seats in business would suit him best. Flight duration approximately 10 hours.
Anyone out there flown long haul with a toddler - what would you advise?
