ANA Award callendar accuracy?
I am trying to book MIA-DEL-MIA using US miles ...ANA award callendar based on my posts researched here seems to be the best way to check for flights.....when i plug the individual flts MIA-FRA (LH463) + FRA-DEL (LH760) and their corresponding returns for dates Sept 12 out and Oct 29 back; the individual flts are avail. in F, however when plugged in as a complete RT MIA-DEL-MIA ?? only Y shows up as avail?????? anyone with any ideas/experience with this kind of issue????
