Hi, I have an itinerary on Condor from FRA to TFS (Tenerife Sur). When I was booking it (economy light), I've seen an option to purchase additional carryon for 16.99 Euro, but now I see that it costs 24.99 Euro. Should I purchase an additional carryon? I have standard US/EU carryon + a messenger bag a "personal item". How strict are they? My ticket includes one "personal item", which says 40x30x10, but I need to pay for additional carryon with size of 55x40x20. I'm slightly more than 48 hours before departure.
