In Pakistan buses are the cheapest but most uncomfortable and dangerous way to travel. By air, PIA has many flights between Lahore and Islamabad / Rawalpindi. Islamabad is about 10 miles from Rawalpindi, the airport is actually at Rawalpindi. Good rail service between Lahore and Rawalpindi, see http://pakrail.com use Lahore Jn and Rawalpindi.
