Definitely double check that the plane is actually what you're expecting. If it says it's operated by a different airline, treat it as THAT airline, not the one selling tickets.

If you have a connecting ANA flight out of Haneda make sure it's not at a different terminal.

Reserve seats in advance. This is an air ticket worth paying for, even if the price is slightly higher. The standard is consistent. Do book your layover accommodation in advance. I booked upin arrival and only got a more expensive option. Otherwise, I enjoyed very much flying with ANA and will choose it again.

  • To enjoy the lounge facilities at IAD Airport, consider booking your flight with United Airlines or Turkish Airlines. These are the only airlines with a lounge at the airport and also offer flights to Japan.
