Forgetting to make sajda-e-sahw

Q: I forgot to perform sajdah sahw which was wajib upon me during the first 4 rakats of sunnah namaz. Then I started Fardh namaz and once I finished fardh namaz I realised that I forgot to perform sajdah sahw for sunnat namaz. Is it permissible to perform the missed sajdah sahw of the sunnat namaz after the fardh prayer?

Travelling without a mahram

Q: I want to go to visit my parents after two years. I don't have enough money for traveling with two persons. I live in Canada and my parents live in Pakistan. If I go alone to Pakistan with complete pardah, is it permissible for traveling because tickets are two expensive.
