"Alaska Airlines' A70 code is listed on corporatecode.org and confirmed across major aggregators. Airline employee codes as a category carry Medium risk — hotels are accustomed to airline crew and employee rates and occasionally verify crew IDs, especially at airport-adjacent properties. The A70 code is alphanumeric rather than a pure 3-letter ticker, making it slightly less prominent in code-sharing communities. No specific forum discussion found documenting elevated enforcement. Standard airline-sector Medium applies, with higher risk at SEA-TAC corridor properties."

"I wanted a higher room floor at a Seattle area hotel. I requested it at the front desk when checking in. The front desk thanked me for being a platinum member and told me that the hotel is fully booked and no “upgrades” to a higher floor for me. The girl behind me checked in and she was thanked for being gold, and they gave her a free upgrade to a suite and let her choose which room she wanted! I asked about the upgrade and they told me it’s random. I spoke to the manager and the manager said lots of rooms available and she gave me 5 rooms to choose from. 🤷🏻‍♂️ In the end, I got my upgrade. Had to fight for it."

"I have a close friend who is a GM at a Marriott property in a fairly large US city (top 25 metro population). Their opinion is basically, "Hey, it's business. I'm not turning away a paying guest if they don't have the right ID." In this person's younger days as a front desk agent, they enjoyed catching people trying to use a corporate rate that the guest was not entitled to. As they became higher up and saw the books, occupancy rates, etc... Corp ID's became far less important than filling rooms."
