Delta offers rollover miles so flying this year will count towards status next year, with current status already extended. Extended status isn’t a disincentive to fly Delta.
Hilton has now updated their rollover nights program along the lines that Delta announced: all nights earned in 2020 will count towards earning elite status in 2021 for your 2022 elite level.
Elite rollover nights provide a faster way to earn elite status. Starting at Silver, at the end of the calendar year, any qualifying nights in excess of those required to qualify for your elite status level will be counted toward your elite status qualification for the following calendar year (January 1st to December 31st). UPDATE: All nights earned from stays in 2020 will automatically be carried over to the 2021 calendar year.
If you already stayed 10 nights in January and February, 2020 those nights will start off yuor elite earning next year. If you stay 5 more nights this year you’ll begin 2021 with 15 elite nights.
Hilton Diamond isn’t much better than Gold, since they still haven’t rolled out confirmed suite upgrades. And Gold is mostly a giveaway level, available with the mass consumer card. It’s valuable for breakfast, and outside of Asia that’s mostly it.
That makes it easier for Hilton to inflate its elite ranks. However the move does put pressure on other programs to at least consider matching.
Since Marriott gave members half the elite nights needed for their current status level I don’t expect them to bring back rollover nights, though it’s a good way to incentivize travel. (Like Marriott, Southwest Airlines gave members partial credit towards elite status and companion pass.)
And since Hyatt gave out extra qualifying miles for spend on their credit card, and already gives out incremental rewards for every 10 qualifying nights I don’t see them matching (though wish they would!).
That leaves IHG as the most likely to follow suit, since like Hilton their elite status is of limited (and even less) use.
