I 'lost' my 48k miles this year as have not flown in 2 years. Have until end of September to take a flight to have them reinstated. I live in France (TLS) so could do a same day trip to get them back. I moved all my business to BA so unlikely to earn any more miles - with all the new changes are the 48k miles worth the effort and expense or should I just drop them?

Thanks...
