AFAIK there is one positive, randomized trial for a nasal spray containing Iota-Carrageenan (Carragelose): “The incidence of COVID-19 differs significantly between subjects receiving the nasal spray with I-C (2 of 196 [1.0%]) and those receiving placebo (10 of 198 [5.0%]). ” It is available at least in Europe, and in the UK I think under the brand name Dual Defence. Why it has not received more attention is beyond me.
I had not heard about nasal sprays being possibly useful. Sounds like there’s preliminary in vitro evidence and a couple of case studies: https://www.biorxiv.org/content/10.1101/2020.12.02.408575v3.full https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7645297/ Though I’m confused about why there isn’t more evidence either way given the first info came out in 2020.

Perhaps CEA could buy some and have them on offer at check-in?
