I hate eating the crappy air-port/plane food, makes me all bloated and now days it's not always complimentary, but quite pricey...
I rather eat a falafel or something when Im on my way to or from the air-port... Maybe a coffee and sometimes hard liquor on the plane, at least if it's a stressful flight...
You know you can bring those cheap mini-bottles from the tax free on to the flight because they are small enough, drives the airport-security a bit mad but as long as the bottles are under 1.7 ounces, they can't steal them from you and throw them away...
And you can enjoy affordable "vegan cocktails" to make your plane-ride go quicker...
