Leaky, uncomfortable (not painful), wouldn't set right. In 3 different airports I tried and tried again. On the 8 hour flight, I went up and down to the mini bathrooms to try again. Eventually I got it positioned (in our 5 of the 8 hour flight), so there was a "reasonable" amount of leakage...Again I'm assuming it was the 40,000 feet but seriously?!
Anyone else have similar issues on flights? Any suggestions?
p.s. Now that I'm off the plane, me and my cup are copacetic.
