Im pretty sure , that what ever deal Fr have got to come to LBA, Ls will be looking to get equal or more favourable deal, People do have choice,thats the wonder of the internet
THere will be pax the will try Fr and love them others will hate them, Im not a fan, but can say i did have a fairly reasonable flight with Fr last month, wouldnt not recommend them as i hadnt got any complaints, not over keen on the mountain of charges, but you do have to keep your wits about you not to get caught out on them when booking, not saying Ls are any better that way , but do think you have better chance getting to or from your destination should there be a problem with ls rather than fr.
