There is some date of birth mistake(month & year same only date is different) in my child visa, so they straight forward denied boarding, they said you have to apply new visa and i applied but my visa not came on time so i change date of birth in my daughter's visa and showed him then they gave me boarding pass, at immigration i showed my daughter's actual visa and i asked this thing to immigration but they said your child is infant so it doesn't matter
Also it is full service Airline but leg space is very narrow
