We indeed arrange all in-country/domestic plane and train transfers. As a fully-certified travel company here in China, we receive much better rates than available externally. We also specialise in such group bookings, so we are accustomed to arranging adjoining seats etc. for the whole party, which is certainly advisable when possible.
We can also assist with international tickets, although we do recommend also shopping around for quotes in your home country. Our priority is that you receive the best possible rates. There are several US-based student flight companies we often recommend.
