Please do your homework before buying Lifemiles. It is what it is... for some that's useful, for others it's not.

Biggest complaints are about
- mixed class bookings are available but now many of the suitable connections dont show
- not being able to book anything that isn't available online (there are work-arounds, see screenshot method below)
- the quality of the call center (English speaking agents are scarce, you might get thrown in a loop with call transfers within their call center)
- no stopovers (>24H) or open jaws, but you can book one way awards
- no reservations on Certain subsidiaries of Star Alliance carriers (Lufthansa Cityline, Germanwings)
- no availability showing at all on the website (try logging out and logging back in)

Problems with ticketing / lack of confirmation screen or email
- write down the confirmation number shown on the screen after confirming your purchase.

Sometimes, even if you cannot see the PNR, the record may have been created, so better to call them and give them flight details you were trying to book. They can find the PNR from those details.
- ticketing usually takes place within 10-15 min of booking
- but it may also take up to 2 days
- if miles have been deducted from your account and a temporary authorization has been placed on your CC, you're probably fine even if you did not see a confirmation screen
- if no e-ticket number is visible on checkmytrip.com after two days, you should contact LifeMiles. You can expedite the ticketing by emailing with your booking reference to: [email protected] after you have booked, especially if you have booked last minute flights, and need ticketing straight away

Screenshot method.
So, on a date you are looking for in the future, there is availability for LAX-NRT and NRT-BKK. But not LAX-NRT-BKK.
It may be a case of the LM system not offering the through connection.

Take three screen shots - two 'available' screen shots for LAX-NRT and NRT-BKK and the 'not available' screen for LAX-BKK.
Send them all off with a scan of your passport page (PDF) and LM will make the booking manually for you.

You need to have 40% of the miles in your account for them to make the booking. On some occasions, credit card points do not transfer over immediately. In such cases also send screenshots of the points being debited from your credit card. In some cases the LM account will immediately show the points transferred in the account activity section. Send a screenshot of that as well.

After a day or two, you will get a reply via email saying the matter has been escalated to an internal area. The next day someone will call you from 305 447 2819 and will process the payment over the phone. You will need to set a PIN which you can do in your online LM account (under the account access section of your online profile).

Send to these two email addresses, and CC yourself (just for your records)
