Firstly, apologies if this is posted in completely the wrong place, couldn't think of anywhere better though!

I'm booked to do the following itinerary soon and am a bit concerned about the connection time, so thought perhaps someone here would be able to give some advice, thanks in advance.

The plan is:
MU2668 LYI-HGH (Arrives 17:15)
KA637 HGH-HKG (Departs 19:10)

I've actually got a colleague who has made this connection before, but he only had hand luggage and I'm going to have a checked bag. Have I got enough time? He said you have to switch terminal (Domestic to International).

I'm unsure what the agreements are between the 2 airlines regarding checking baggage through for both segments, I guess this would alleviate some of the risk if possible.

Thanks for any help, I want to try to avoid being stuck somewhere for a night if possible!
