Comparisons
KrisFlyer vs MileagePlus
The held fields separate these two programmes on operator and region, aside from the names themselves: KrisFlyer is Singapore Airlines in Singapore, while MileagePlus is United Airlines in the US. Sector, currency and tier presence are identical, so the register gives no mechanical reason to rank one above the other.

What each is built for
KrisFlyer and MileagePlus are both airline loyalty programmes that accrue in miles and run elite tiers, so the held fields give neither one a mechanical advantage over the other. The separation is in operator and home region, aside from the names shown: Singapore Airlines in Singapore against United Airlines in the US. In practical terms that means two airline networks with different hubs, not two different loyalty designs. A reader whose flying is tied to Singapore Airlines is looking at one route map, while a reader whose flying is tied to United Airlines is looking at another. The sector, currency and tier fields are identical, so beyond that operator link the register offers no basis for calling one programme more generous, more premium or more useful.
When to choose each
Choose KrisFlyer when the flights you actually pay for sit on Singapore Airlines services or connect through Singapore, because the register links this programme to that operator and shows no alternative earning path. Since the sector is airlines on both sides, the question is not whether an airline programme fits your travel, but which carrier you board most often. If your spend already follows that network, holding KrisFlyer miles keeps the earning and redemption path on the same operator, and the Singapore region is simply where that operator sits.
Choose MileagePlus on the axis of what you already hold or can use, not on where your next trip touches. The register shows the same miles currency and the same tier structure, so neither side has a held advantage in transferability or tier power. If your balance and status already sit with United Airlines, continuing with MileagePlus preserves their usefulness without assuming any unheld benefit. The absence of earn and redemption data makes continuity of the account you hold the only rational tie-breaker on this axis.
What this register does not hold
The fields that would actually settle this comparison are absent: earn rates, redemption values, tier benefits, award availability and fees. Without them the register cannot say whether a Singapore Airlines mile buys more than a United Airlines mile, whether one elite tier grants better seating or lounge access, how many award seats either scheme releases on a given route, or what an award costs in cash on top of miles. Those missing facts are the real decision inputs for a loyalty programme, and no held field here can substitute for them.
