I’m familiar with OW airlines such as MH, JL, and BA who all offer something similar. Which *A programs allow elite members to gift status to a spouse or partner? Here are the ones I know:
TP for their Gold gift +1 Gold
UA for their Million Milers gift +1 Gold/Plat/1K/GS (status equals that of primary)
SA for their Lifetime Plats who achieve an additional threshold gift +1 Gold
SQ for their Solitaire PPS Club gift +1 Solitaire PPS Club Supplementary
SK for their Diamond gift +1 Gold and +1 Silver; Gold gift +1 Silver
LH/LX/OS/SN/LO/OU for their HON Circle gift +1 Senator
NZ for their Elite gift +1 Elite Partner
TK for their Elite Plus gift +1 up to 3 Elite for 40K award miles each
AC for their Super Elite 100K gift +1 Elite 50K and Elite 75K gift +1 Elite 35K*
*unlike SK, AC requires this option to be chosen in lieu of other Select Privileges available.
Surely they’re are more options in *A given the quantity of airlines and hopefully with reasonable requirements like TP, who else am I missing?
