T1 to T4s Madrid

I saw your reply to Peggy Mayrn in Nov 06 but am not sure that it answers my question exactly.
In a couple of weeks, my son will land at T1 Madrid and will have 1.5 hours to get onto a different airline connecting flight in T4S. Is this enough time ?
Thanks
Debbie Gibraltar


My reply...


Yes but tell him NOT to hang around.
You should also check with the airline that you are flying out of T4S with as to how long before take off they close the check in desks.
