"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 mean, it depends on the size of the hotel. Having one person on night shift for a Fairfield isn’t uncommon. The better hotels have more people working at front desk even at night simply due to the size and brand. I’d however say though, if the property has been notified of the guest’s check in time in advance, and part of deal of getting into night shift is to check people in at unusual hours like that, then it certainly does not sound right to me that the front desk agent cannot have the meal earlier or later out of that many hours of the shift."

"I now always make it a matter of course to carry documents (business cards of my contacts, e-mails requesting my visit etc.) from my host company when I travel. This has always proven sufficient for the few times I've been challenged by the front desk clerk."
