AI segment on UA ticket with LHR overnite layover
Friend is travelling to BOM on UA ticket with EWR-BOM nonstop outbound but return on AI from BOM to LHR (overnight layover of 21 hours) and then UA back to EWR.
This is NOT a stopover as stay at LHR is less than 24 hours and no extra UK taxes are levied because of it.
This is single UA ticket.
Will bags be checked all the way to EWR by AI for BOM-LHR-EWR portion?
Reasons for asking:
a) Although these are *A partners segment on the single ticket, UA and AI are still different airlines. (Most likely this should not be an issue)
b) Even though layover is less than 24h and hence legal connection rather than stopover, it being overnight an issue about ability to do through checkin?
