U.K. and Ireland - Heathrow - Is 1.45 min enough time for a connection?

I arrive on flight UA924 into Heathrow Terminal 1 at 10:05am. Could I make an Air Lingus flight at 12:05pm in the same Terminal?

Is it on the same booking or on different ones?
When are you travelling?
What nationality are you?

Its a different booking. I have to pick up a bag and go through customs. US Citizen. This is on the 23 of July

Absolutely no way, I'm afraid. Even in normal circumstances it's very tight with checked baggage. But this is four days before the start of the Olympics. They're predicting hours of queuing.

Actually, I'd say opposite. Even though Olympics potentially complicates matters He's traveling UA>EI. Yes, on separate tickets, but both carriers are at T1. UA should be able to check through his bag to final destination. That way, OP stays left at immigration check and goes through security and ends up back in transit area. Goes to EI desk, if he hasn't already checked-in and gets BP and heads to gate.

UA should be able to check through his bag to final destination.

Are you sure they will?

I assumed, since the OP specifically mentioned picking up a bag, that he had already checked with them and that they said "no". There is no guarantee that airlines will interline bags on separate tickets, as I'm sure you know.

I agree that IF UA check the bag through then it's more do-able - but that's a big "if", unless someone knows differently. (And of course there is still the possibility that the OP will queue for hours at Immigration...)

If it isn't on the same booking then I would not risk it. If your inbound flight was delayed you would be left stranded, and neither Aer Lingus nor United would have any responsibility to assist you.

If you are travelling in the games period as well Heathrow will be extremly busy, and factoring in having to collect your bags and re-check in and maybe a Terminal change then you'd have no chance.

Why does Expertflyer treat this as "international to international"?

From a logistical perspective UK to Ireland flights are not international (any more than intra-Schengen flights are). You have to clear Immigration at LHR... and, as we already said, clearing Immigration is likely to take a long time next week.

The results are the same. It is how I enter the search.

Thanks everyone for the feedback. I chose a 2pm flight instead of 12. Now to get the Global Entry to speed up customs/immigration.

Are you talking about Customs and Border Protection 'Global Entry'?
If so, it only works entering the US. It won't help you at LHR.

Across separate bookings I would not expect UA to interline baggage. But he has to clear immigration even if interlined, so I think this is very likely to cause problems.

I agree with your assessment that it's not that likely that UA will interline the baggage (though some airlines do, even on separate bookings)

But why should having to clear Immigration have anything to do with whether or not you can interline baggage? Within the EU I would expect to be able to check my bag to my final destination regardless of where I am clearing Immigration.

I guess I could have put those on separate lines. The fact that he has to clear immigration will be irrelevant to interlining baggage of course, but it also is another delay at LHR that could generate a misconnect.
