My itinerary:
- UA: Indianapolis -> Newark (operated by ExpressJet). Flight# UA**
- ANA: Newark -> Tokyo (operated by UA). Flight# NH**
- VNA: Tokyo -> Hanoi. Flight# VN**
ANA policy allows 2 free checked bags, but UA baggage calculator shows that I'll have to pay $100 for my 2nd checked bag. I tried calling UA customer service and was told they have recently changed their policy. The rep however was unable to point me to the document announcing said change.
However the information here says that the Most Significant (marketing) Carrier policy will override other carriers', which means only ANA policy will apply to my itinerary.
Am I missing something? Can I use this information to fight with them at the counter when I'm actually flying? This is a big deal because my family are flying together and it may cost us over $300 on checked baggage.
EDIT: added flight numbers.
