I know for 2023 there may be many but I like to stick with Delta.....in MSP.....upgrades tough I'm sure but with Reserve CArd too may helps....pay for F when traveling with significant other...for 2024 probably drop to PLT but give it a try for a year....could flip over to U or A but any advice....I suspect many think / asking same question....I'm in it for phone line, sudden scheduling changes, GUC....makes sense or flip and stay at PLT....does it make sense to have one carrier at the top tier?
