[QUOTE=cas_de;26242281]The 4 hr rule is afaik standard for domestic US itins.



I forgot to say that the booking I am talking about is for international travel where there is more than four hour connection in the US (originating in the US) - let`s say
IAH-EWR, then stop 4+ hours
EWR-FRA
some agents tell that such booking is not valid because it doesn`t comply with "4 hours" rule.
