Thank u for your reply David.

I just spoke to my ticket provider, and I will have to checkout my luggage in Beijing and Re-check it again at the Ethiopian counter in Beijing.
Again, my flight gets there at 5:15 and my next flight is 8:10..Do u still think I will have enough time to transfer myself and luggages from T3 to T2 ??
Is the transfer difficult in the airport? I have never been to this airport so Im a little scared.
Please let me know David,
Thank you
