Have an award trip (booked with United miles) SEA-LAX in coach, 2 hours 23 minutes connection time in LAX, then continuing on Avianca (in business class) LAX to BOG. Booked as one ticket. Traveling on a Monday in February, connecting late afternoon/early evening. Will have a bag checked thru.

I figure 2 hr 23 min should be adequate to make the connection (assuming the inbound isn't horribly late), but it's been a long time since I transited through LAX and I don't know it well.

Should I expect a terminal change (United domestic inbound to Avianca international onward)? How long of a slog? I'm also hoping to grab some quick dinner between flights, too, if that's possible (I'm told the food on Avianca's business class is pretty disappointing, so I suspect I'll do slightly better if I can eat something before boarding). Thanks for any insights you can offer on how tight this will be.
