toga737
Whilst it sounds encouraging, it's best to wait until you've actually signed the contract before you breathe a sigh of releif. (This is no reflection on tfly - just experience of aviation in general).
The 6 new NGs are replacing 6 old 757, 767, 737, so no new airframes. The only consolation is that if we fly the same number of pax, an NG will have to fly more often (and use more crew) to shift the same number of pax as a 757/767.
