We just purchased the Evenflo Maestro for our upcoming trip to use in rental cars. We are flying JetBlue, Delta and Hawaiian Air on this trip and I was trying to find out if others were successful in installing this car seat on the regular economy seats on these airlines. The car seat at its widest seems to be around 19" and JetBlue's website says that the widest economy seat maxes out at 18". Same for Hawaiian Air. Couldn't find the relevant info for Delta. We have two toddlers and thus two car seats and we would hate to have lugged around two car seats around the airport only to find out that they do not fit and we need to gate check anyway. Thanks!
