I find this true with me too. Smoke more on vacation and pack a herfador. I also carry a key chain punch. Pack 2 lighters into the herf sealed in a ziplock bag and try to book a balcony. I don't think I'm committed enough for a phone app, but that's neat they make one. I have been carrying around the top to an old coffee grinder for an ashtray. It has a slanted top and long tab to hold my cigar, and fits into a cup holder. I do most my smoking in the car if I'm on a solo trip, and just use the wind to ash, but the ashtray comes in handy for the balcony. I keep the driver's side window cracked, and close the vents to protect the air filter. I always look for rules, but rarely see any smoking rules posted for balconies. Hope I'm not the one motivating them to add them! Never had any complaints though.
