I'm trying to get ahead of this before it becomes an issue. I have an itinerary that is technically a multi-city itinerary: DEN-IAH-TPE-BKK; BKK-DAC; SFO-DEN. This is an award ticket and I booked it this way (with ticketing agent help) in order to get the Excursionist Perk on the BKK-DAC sector. What makes this itinerary (I think) unique, is that there is a 12h50m "layover" in BKK in between the first two legs. The DEN-IAH is obviously on UA, IAH-TPE-BKK on BR, and BKK-DAC on TG.

When I log onto united.com and search My Trips, it comes up that the trip is "initially" DEN to DAC:



When I go to the Travel Ready Center, it then (correctly) splits up my trip into the three segments:




With the middle segment saying that I need a visa, which is correct. But Bangladesh has visas on arrival available for tourists, which is what I plan on doing. The problem is when I click to look at the visa info, it only has information about business visas, not tourist:



And the main issue is that United's TIMATIC info is not the same information that I've seen on other airlines' TIMATIC pages. Pulling from Copa for instance:


What I assume should happen is that United will only check me in as far as Bangkok, since the BKK-DAC leg comes > 12h. Then I'll have no issues, TG will have the correct info as far as visa on arrival is concerned, and I'll be fine.

What I'm concerned will happen is that United will try to check me in all the way to Dhaka, will see that I don't have the proper invitation information from the business entities in Bangladesh and deny me boarding, because they're too stubborn to understand their TIMATIC info isn't applicable.

In reality, this is probably just me being overly worrisome once I see the yellow instead of green on the Travel Ready Center, but I'd rather have my head wrapped around the situation before it becomes an issue.

Any concern I should have here? And anything I can do about it at this point other than print out the correct TIMATIC info and have that ready when I go to check in?
