I see no reason for a r/s before beginning service as well. If they were to have a split before their first dollar is made they would need a 50-1 split just to have a $1 stock price, which is enough to get on the Nasdaq but not NYSE ($5). Regardless, a $1 stock price before they start flying after a 50-1 r/s, assuming the price is an even .02 before r/s, would have a negative impact on the company and its investors.
A R/S would be a mistake in my opinion, ESPECIALLY before revenue flights start, but an r/s would not be optimal until at least they have generated a good amount of revenue and established consistent travel to and from St. Petersburg, and even then I prefer buybacks over r/s.
Just my opinion.
