In 2007, I traveled ORD-HNL on the former UA 1, it was 777 old config - approx 10 hours of flying westbound. We had our 3 kids 4,7 & 8 - bigger than toddler age, but they survived with the array of personal electronic devices. Sat in Economy, actually the bulkhead row with the big pull down screen right in front of them. a bit unpleasant, but they were on waikiki beach by mid afternoon - all good
